It's all about discovery, a journey to find who you really are. Life is difficult when you don't know, and you'll wander and you'll hurt because you cannot fathom why you can't be who you want to be. Changing the attitude you've always held is not easy, and it's even harder when you don't know who you really are and what you really want. Are you as good as you liked to think? Are you worse? Do you have fun? Are you alone because you want to be?
Project yourself in the way you want to, if you know who that person you want to be is. Some spend their lifetime not knowing who they are, others always just knew; the rest take the time to try learn. Some succeed, some don't.
The only thing that's certain is that you cannot love anyone else without first loving yourself. And I'm not really sure, am I the type of person that I can love? Windows of opportunity open, it's time to start stepping through.
