Look cool. Lean against a wall, or, if a wall isn't handy, against air.
Always wear sunglasses, and try very hard not to bump into things when indoors.
Ride a motorcycle everywhere, including indoors. Make sure you know how to ride first, though, as horrific crashes aren't very suave.
Learn to wink, and replace blinking with winking. It may look like you have a facial twitch, but keep at it. It'll look cool eventually.
When in doubt, just mutter something about being ironic and leg it.
In all seriousness, just be confident while not overconfident. Good luck finding that balance, though it's easier than leaning on air.

Good hygiene is important.
After all, cleanliness is next to godliness.
"Classically, very few people have considered that cleanliness is next to godliness, apart from in a very sternly abridged dictionary."

Sorry, mate, saw a chance for a Terry Pratchett quote and couldn't resist.
