So here is a situation I get all the time at salsa congresses. There are many awesome dance partners available. I have been trying to get a dance with a particular (but way too popular) dancer. I refuse to get "in line" behind all the other guys waiting for their opportunity. I don't want to miss out on all the other equally awesome dancers and songs. They may be (and usually are) just as awesome without the wait and the opportunity cost of a missed song. There it is: my return on dance investment advice. Anyone else ?
