I feel like being nerd is not about the superficial quality; it's about how nerds approach life. It's much more emotional and mental than it is you're some fat guy living in your mom's basement, which I think is just a hacky stereotype.
You have to feel comfortable being uncomfortable. I'm always comfortable being uncomfortable. And to be comfortable being uncomfortable, I have to hone my discipline, which to me is doing what I have to do, but also doing it like I love it.
