The Selection Criteria

I have selection criteria for whether i choose to pursue something or avoid it, leave it to some one else. And i would certainly say that some signes of demand is part of my selection criteria. Could i do this with as short amount, with a small amount of investment? Nowadays i'm a bit more strict. I avoid things if i feel like i would be not enjoying them,. Or they would be er something i wouldn't be looking forward to doing in the first place. It's a great litmos test to keep things simple and get into complex partner ships.
