It's okay to take that reservoir of passion that you have and let it flow into whatever you love. Experiment, question, replicate, be critical, be nerdy, be yourself.
Be yourself. You're okay. And it really doesn't matter what other people think.
The most important advice you can give anyone about to appear on TV is incredibly prosaic - be yourself.
It's just better to be yourself than to try to be some version of what you think the other person wants.
I found out in pro wrestling that it works better if you just try and be yourself versus working on something you're not, so I'm me, and maybe it's magnified a bit, but it's easier just being me.
Always be yourself and rebel against what people tell you should be and be whatever you want to.
