My biggest thing? No, but it's up there with my biggest thing(s): Music, martial arts, photography, cars, hiking and a few others. But, I'd say my biggest thing is advertising and that incorporates all of my other "big things." Hell, I get to do so many cool things as an ad creative it's insane people get paid for this {censored}. The more useless knowledge and life experience in other fields that you have, the better off you are in this industry. It's sweet.
