If you could write a note to your younger self, what would you say in only three words?
I had two thoughts. 1) Words can hurt. 2) Try your best.
What would your note say? 
Don't be so hard on yourself
Don't be stupid.
You should never feel ashamed about yourself and you should just live up to your full potential. The people who don't like will never understand, you can choose to walk away from them but if you want to please them, you will never be able to understand or like yourself at all
Focus on YOU. Your physical and emotional health. Take care of YOU.
A letter in for my younger self, why that is nearly impossible counting up all my mistakes, if i had to sum it up tho... JUST DO IT!!!!!
Hang in there. The ride gets bumpy but it's worth it!!!
Don't be afraid to take risks. And ask the girl you like on a date before it's too late and she marries someone!!!! Dammit
never get married
You're almost there
Don't be afraid
