Intro I Guess?

I always wonderd if every girl thinks the same thoughts or if we ask the same questions.

What am I going to do when im older?
Am I mature enough physically and mentally for a relationship?
Should I watch youtube videos until 4am?
Do I actually look this unattractive?

I always kept a journal on hand so I could document my feelings but lately a bigger question has caught my attention.

Are these thoughts original or does every teenage girl have similar thought provoking questions?
