This here is a very inspiring and brilliant post by a man called Kevin Kelly who speaks about the idea of creating '1000 fans' as your sole form of livelihood. In that, once 1000 true fans have been made, you can easily live and create off that base.

It is a memorable post that has infiltrated my thinking lately.
