Life isn't about finding yourself, It's about creating yourself.
When you get to a new place or when you leave something behind you intend to change. When you then realize and people realize that you are changing, most of the time people try to find themselves again. the thing is, DON'T.
I believe at this age you should never go back and try and find who you used to be. Maybe if you are going through a midlife crisis, then fair enough. But if you are just an ordinary teenager whose stepped into adulthood, then don't. Let yourself develop and bloom into this new individual. You values are going to be changing when you are experimenting with the new environment you are in. Especially if you just moved countries, for college or something like that. Try to be different. You might end up valuing yourself alot more. Maybe not. But then every time you meet those from your past, the ones that made you into the person you were then, things will always be the same. That is the beauty of being a human, that you are flexible to change.
Dare to be something different. Dare to change your life.
