1. Take risks that matter ( like asking the girl/ guy out) but not stupid shit like joining a gang or something
2. Finish school ( high school, university, and all that jazz)
3. Join a lot of extracurricular activities at school because honestly you learn more outside of the class room
4. Realize you are young and beautiful even if you don't believe it now
5. Make mistakes, act stupid because you are young and mistakes teach you important lessons but don't get knocked up, murder someone, overdose on drugs, end up in jail or commit suicide ( these mistakes you can't erase or fix and have a finality).
6. No one will remember the mistakes you make 5 years from now (aside from the ones that bring a finality or consequence that can't be overcome) ..so relax.
7. That boy/ girl that didn't like you in 5th grade will ask you out in high school
8. Plan for your future now so you can have a head start when most of your peers are still trying to figure it out and are going through an existential crisis.
9. Heartbreaks are not fatal.
10. Learn to love yourself... this is the most important lesson of all. You need to love yourself so you can believe in yourself. Self doubt doesn't lead to accomplished goals.
