Yes and No. But honestly, The only GREAT LESSONS REMEMBERED are from the things we did (poor/wrong) choices that we made, that caused us the most pain.
Every day i wish i could be 16 again and re live that beautiful time in high school and maybe change a few things here and there. But then again i wouldn't be the great person i am today, thanks to all that experience i have matured to become what i am now.
