At the very least, you can live knowing that you ended up where you are in life because of who you are, not because of something you pretended to be. I have a techy friend from Harvard class of 2006, but he didn't want to be thought of as a nerd when he got there, so he pretended to be an alpha banker type instead.

Well, fast forward 10 years, and no one bought the alpha schtick, and he missed his chance to be a billionaire working with Zuckerberg.

You never know how positively the world is going to react to you being comfortable and confident with yourself.
