I usually find creative inspiration in the works of peers or superiors. The creative works of peers makes me want to compete against them to make something better, sounds a bit aggressive, but that's how it goes for me. As for superiors, I aspire to be able to make works that are the same if not better quality.
Whenever I see BBoys my age that are cocky, I get the urge to get better than them (if I'm not already) and crush them to show them their place on the ladder. People have to realize that they're not the best and just because they've earned some others' approval doesn't they've earned everyone's approval. This is straying a bit but basically I get inspired from competition and better creation.
