It's a joke, sure. But it's more true than most people want to admit.
I'm an emotionally independent guy. I don't think about things I can't control and I don't seek social validation. I try to be good. I'm a dreamer. I'm an introvert. I'm even tempered, never angry, and I laugh often.
I know what I like and what's important to me: art, science, technology, fitness, swimming, great food, bad food (I'm probably a food addict by the way).
