If you're serious about getting paid to perform then you have to:
1) Define your target market
2) Determine the people you WON'T perform for
3) Find out how your buyers buy
First you have to determine what type of market you want to perform for.
After you have done this, you want to create a velvet rope policy by deciding who you won't perform for. If you accept any gig that comes your way then you will never develop the psychology of a successful entertainer.
And finally, you want to know how your buyers (the people that hire you) buy. Each target market buys entertainment differently. If you know your market then you need to know how they hire entertainers in that market.
