I'm definitely an introvert but got plenty of notches during college through my twenties playing in regional bands.
So this is probably more a local version of 'fame game' more than anything.

Advice to introverts: Know, find, or develop your talents as early as you can. (Mine were art and music.)
The better you get at something --> more people notice, widening your social net.
Confidence comes from competence, pushing aside introversion -- at least for a limited time.
