You didn’t develop your character because you did everything right.  As  that rickety old woman told once you, flowers grow in the valley, not  the mountaintop. And you have to walk through the valley to get back up  there.

So, make your mistakes. Kiss the wrong boys, overdraw your  account, and trash your grades. What you do right or do wrong over the  next fifteen years may make you grieve and may make you shine, but they  won’t necessarily have anything to do with who you are, and that is the  most valuable lesson you will learn.
