Being yourself is a challenge in a world where everyone wants to be like everyone else.
We are all created differently and to me there should be power and comfort in that. With that said people fundamentally want to be wanted and the unfortunate thing is that those who choose to be themselves in a group risk rejection.
The older you get the easier it can be in some ways, however you still have to go with the flow in some situations as it relates to work and that sort of thing. One thing I have learned is that everyone has value and a purpose in this life. Be the person you are designed to be because the world needs you to do that. I can think of a kid who is growing up who feels alone because he wants to go his own way. That is the kid who needs support and affirmation that he is awesome. So, your challenge is to be yourself and to help others do the same.
