When your body starts changing as if by magic, when your emotions swing like a roller coaster, and when you find yourself at the crossroads of your first major life choice, I know that sometimes you feel like a computer having its System reinstalled: pop-up windows everywhere, background processes in chaos, and the occasional crash. Don't worry. All of this is normal. Welcome to adolescence, a somewhat messy yet incredibly wonderful period of rebuilding that everyone goes through. This book won't lecture you in a stiff, solemn way, or brush you off with "Back in my day." Instead, we'll sit down like friends and use scientific data, real stories, and a little humor to unravel the mysteries of "Why am I like this?" one by one.
