I've always had a mindset that I can truly accomplish anything I wanted if I can visualize it. Call it cliche, but you need to have that mindset in order to be successful at anything that requires passion. The 'work' involved in pursuit of reaching those goals is the best part about that journey. Wanting something bad enough, you forget about the risks involved or anything that can go wrong. Failing is the key to success, and that's why it's worth it at the end.
I'm also big on having a sense of humor. I can laugh at myself and laugh with others...but all in good fun ;). Being sarcastic is part of having fun, and what's life without sarcasm.
