"Paul Graham, Jessica’s husband and partner in Y Combinator, has tackled this subject on his website. “The biggest reason founders stop working on their start-ups is that they get demoralized,” he writes. “Some people seem to have unlimited self-generated morale. These almost always succeed. At the other extreme, there are people who seem to have no ability to do this; they need a boss to motivate them. In the middle there is a large band of people who have some, but not unlimited, ability to motivate themselves. These can succeed through careful morale management (and some luck)."

I’m somewhere in the middle.I have some ideas around companies that the world needs, that would survive (none of them are going to be the new Facebook, but they would service a need), and that might even make me some coin, but so far I’ve only been motivated enough to get involved in 2. I have another 6 ideas or so (Medicine, Charity, Apparel) where there is a lack of market or skills, thereby an opportunity for some coin via arbitrage.
