A couple of months ago I've just started to live by my own because I got a better job , far away from my family where I had everything.... Well almost everything :) Now feel like I'm getting more responsible everyday... It's an excellent experience, I personally think that you start to become an adult when you learn to be completely independent ;)

You need to learn how to be independent. :P

Get out of the house, get a job, make your own decisions and learn from them, don't let the pressure get into you, be happy, set life goals and accomplish them one by one...

Finally, experience the life you want for yourself,

don't let others tell you otherwise.

Never forget how awesome you are and love yourself always,  self confidence is an absolute must (you can practice and learn to be self confident if you don't feel you are), don't be afraid to try new things, take risks, always be open to others: everyone, everywhere, always! Don't let people take advantage of or mistreat you, fear is the enemy of good and inaction the acceptance of fear.  Failure will happen and if you don't occasionally fail you're doing something wrong, learn from it and become better. Those are just a few things I've learned along the way, hope it helps!
