Being yourself isn't hard. Many people find it hard because others tease them for it, don't like them for it, or other reasons that break them down.
Well all you do is you don't think of what you should do or what you should say to something, don't be afraid!

When you walk straight with your head up you will see that your confidence is starting to build.
In order to become confident you must LOVE your walk, you must LOVE your talk and you must love you
A simple rule is you must not change EVERYTHING about you.

Alot of people who sit there waiting for you to comment about their comment on you must not be being them! You know why? It's because they wouldn't care! Usually people who worry about commenting on YOU are always the ones who are insecure themselves.

A secret I never told anyone is to never care, if you feel fat just jog! It shouldn't stop you from eating less, you must feed your weight though! Dance! Who cares?!?
When you don't even SHOW your shyness everyone will love you more
