What advice would you give yourself if you can go back to age 16?

obviously i want people older than 16 to answer this (specifically adults, please).What advice would you give yourself if you can go back to age 16?
I'd tell myself to slow down and enjoy being young. I was so eager to grow up that I rushed through everything. Now looking back, I wish I had taken my time .What advice would you give yourself if you can go back to age 16?
i lack self confidence back then and i worry too much and very shy. i got matured so soon that i would advice myself if i'm 16 again to be more outgoing, develop the talent that i was given. concentrate more on my studies, pay a little attention to boys and join all the activities in school.
People do care, notice you. Just because they don't talk to you doesn't mean they don't care.





I've been thinking about my junior and senior years in high-school recently
