2017 goals


the clock has struck midnight- it's now 2017! happy new years! have you decided on your resolutions? do you believe in resolutions? are you going to keep your resolutions?


i've always thought that resolutions were kind of lame & unrealistic bc no one ever really keeps them so instead, i set goals for myself. these aren't exactly things that i want to achieve in 2017 but things that i want to work on/work towards.
  1. be healthier- eat a little bit better, drink A LOT more water (pretty self explanatory)
  2. draw more- just doodle/sketch something once a day (i hardly draw anymore but i'm gonna need to work on that if i wanna major in art, yikes)
  3. spend less time on social media- go find something better to do (all i do is go back & forth on apps when i'm bored, even if there's nothing new, i need to stop)
  4. live my best life (discussed in my last blog post)
  5. be the best version of myself (i'm not satisfied w the person i am but i'll get there)
  6. connect more- reach out to people, stop being so afraid (& stop shutting people out)
  7. break out of my shell- i need to stop being shy & awkward  (so many missed opportunities)
  8. put myself first- all i do is put others first & try to make them happy (it's time to focus on me)
  9. stop stressing myself out- not everything is worth stressing out about (i stress so much, i'm my own stressor)
these are my top goals for the new year & i'm posting them bc people say that written goals are more effective (technicially this isn't written but i'll copy it down in a notebook, so same thing). i'm also posting it bc i think i need people to see my goals, know that i want to change, & hold me to it- even call me out if necessary. hopefully i'll be able to change some things in my life in order to meet these goals. i don't have to become a health freak, draw 24/7, delete social media, become an extrovert, etc.- as long as i get closer to my goals. baby steps are okay. progress is progress no matter how small.

reminders for living your life in 2017

we all have those things that we know we should do but we don't do it, or the advice that we should take but we don't. why don't we? why don't we do the things that will help us live our best lives? i'm definitely guilty of this & maybe w the start of the new year, i can push myself to do these things that i know i should do. i want to live my best life, everyone does. here are so reminders (that i found on tumblr) on how you & i can (this list is for me but it can really be for anyone) live our best lives in 2017: 
  • don’t let shyness overcome new opportunities
  • put your needs first- it isn't a problem for those who truly care about you
  • live fearlessly
  • pursue joy
  • cut toxic people out- you'll feel like poop at first, but later you will feel relief & freedom.
  • calm down before making decisions in anger
  • stop trying to please everyone- it's impossible
  • drink more water
  • stop caring so much about what people will think & say
  • don’t knock it ‘til you try it
  • it’s never too late for an apology
  • be cool to younger kids- reputations are built over a lifetime
  • be a good listener- don’t just wait for your turn to talk
  • make the little things count
  • do what helps you boost your confidence & self-esteem
  • stop procrastinating- no matter how unmotivated you are
  • be honest, be honorable, be kind
  • allow yourself the time to acknowledge how tired you are- allow yourself room to be real
  • be so comfortable with yourself that you’re unafraid to do things alone
  • smile & laugh more- there’s always a reason to smile
  • choose to love- yourself, others, & the world around you 
  • stop giving people the power to treat you like you mean nothing
  • it’s okay to cut off people from your life- your well being matters more than anyone’s
  • forgive & let go- grudges make your heart ache & drain your energy
  • don’t overthink every single thing
  • appreciate & embrace what you have
  • make sure you’re ready to face consequences before you make impulsive decisions
  • do not give so much of yourself to people who will not do the same for you
  • strength isn't about succeeding or failing- it’s the fact you battled on despite your struggle
there are probably so many other ways that we can improve our lives too, but the goal is to be so busy living a good life so that i don't have the time to find them all. the countdown until 2017 begins:

wrapping up 2016- good? bad? worst year???

the year is coming to a close & wow, it was a doozy. everyone is calling 2016 "the worst year" & i'll admit, a lot of bad things did happen- just to name a few:
  • the death of george michael
  • the mess that was the presidential election
  • the death of christina grimmie
  • the orlando shooting
  • the death of alan rickman
  • zika
  • the death of carrie fisher
there were really a lot of deaths recently, & not only of celebrities but my grandfather also. however, we can't just think about the bad, we have to focus on the positives: 
  • the breakthrough in research for ASL
  • finding dory
  • NASA got into jupiter's orbit
  • the hilariousness that is deadpool
  • harriet tubman might/is supposed to replace andrew jackson on the $20 bill
  • zootopia
  • the manatee population is no long endangered
ofc my lists are short since i can't possibly know every good & bad thing that happened in the world but who's to say whether the bad outweighed the good or vice versa? all i know is that we have gotten through a tough year & we're headed into a new one. let's try to stay optimistic, even w all of the bad that has happened. i can't wait to see all of the good that 2017 has in store.

MD & R.I.P 12/15/16


the countdown until MD starts again! 

earlier this year, in the summer, i already went to MD. but due to my grandpa's poor health, we decided to go again in the winter to visit him. we were planning to go on Christmas morning but unfortunately, his health only got worse. we re-booked to an earlier today, Dec. 17th (today, technically) but unlucky us, he passed away 2 days before the day we were supposed to go back.

12.15.16 // we all love you so much ong ngoai. we would have been there in 2 days but God just couldn't wait to have you back w him. there are no words to even describe how much we will miss you. rest in peace grandpa.


this is very saddening but i am still excited to go to MD. my family needs to all be together to support each other during this sad time & i can't wait to see them. i truly appreciate all the prayers for my grandpa from my friends & family. all we can do is try to remember that he is in a better place now.

on a lighter note, since this semester & finals are over, i will definitely be vlogging again, especially since i'm going to MD so watch out for new content!

thank you for all the love & support <3

student exhibit // my artwork got second place design!

guys. i am excited & i just thought it would be nice to share a little piece of my happiness w the internet.

so every semester, Lone Star has a Student Exhibit in it's Bosque Gallery.
it is still open, until Dec. 12, 2016. MWF- 10:00AM-1:00PM. TTh- 2:30PM-5:00PM.


my art professor told me to submit some of my artwork to the Student Exhibit so i submitted 2 of my best artworks- "the art of Fishing" & "indigenous."


so i walked into the gallery one day & bam, my 2 pieces were right in front of me & i saw this little red tag under "indigenous" so i went to go look at it & you probably can't read it from the picture but it says "second place design."
i got second place design.


today, i walked into my art class & my professor gave me a certificate for second place design, but that's not all. another art teacher came into the class & told me that the school might possibly want to buy "Indigenous"!!!!!! i mean, there's a whole process that the art committee has to go through & there's always a chance that they don't buy it, probably, but i refuse to let that hinder my excitement. my artwork has buying potential!!!

ch. 16 | the reproductive systems

  • gonads: (ovaries & testes) produce gametes & secretes hormones 
MALE:
functions of male reproductive system:
  1. testes produce sperm & the male sex hormone testosterone
  2. ducts transport/store/assist in maturation of sperm
  3. accessory sex glands secrete most of the liquid portion of semen
  4. penis contains the urethra, a passageway for ejaculation of semen & excretion of urine 
male reproductive organs:
  • foreskin (prepuce) is removed during circumcision
  • the spongey (penile) region of the urethra fills with blood, causing an erection 
  • sperm production begins during puberty & continues throughout life
  • meiosis: cell division that occurs during production of gametes which receive a set of 23 chromosomes each
structure of sperm:

path of sperm through reproductive tract:

FEMALE:
functions:
  1. ovaries produce secondary oocytes & hormones (estrogens, inhibin, relaxin, etc.)
  2. uterine tubes transport secondary oocyte to uterus & fertilization usually occurs here
  3. uterus is site of implantation of fertilized ovum, development of the fetus, & labor
  4. vagina receives the penis during sex & is a passageway for childbirth
  5. mammary glands synthesize, secrete, & eject milk for nourishment of the newborn  
female reproductive organs:
  • labia: hair-free fold of tissue next to the urethral & vaginal orifice 
  • there is no tube that sends ovulated oocytes from the ovary directly into the uterine tube
anatomy of breasts:
  • lactation: secretion & ejection of milk by the mammary glands
  • fertilization must occur while both the egg & sperm are still viable 
  • pregnancy lasts from fertilization to delivery (38 weeks)
  • due date is calculated from the 1st day of mother's last menstrual period which occurred 2 weeks prior to fertilization
  • embryonic period: fertilization-8 weeks
  • fetal period: 9 weeks-birth
  • zygote: single cell resulting from the union of make & female gametes; fertilized ovum; contains 46 chromosomes (23 from ovum & 23 from sperm)
  • labor: process of giving birth in which a fetus is expelled from the uterus through the vagina
  • parturition: act of giving birth to young; childbirth/delivery 
  • breech position: heads up or sideways orientation 
stages of labor:
  • puberty: time of life during which the secondary sex characteristics begin to appear & the capability for sexual reproduction is possible; usually btwn ages 10-17
  • menopause: termination of the menstrual cycle
