The incentive is in the mind of the beholder. $42,000 captured the mind of the author; for its promise, he worked extremely hard and long, mustering a productivity far and above what he normally would have achieved. Then, when he in fact received not $42,000 but $3,666, less than one-tenth what he expected, he convinced himself that this was not a loss but a win because $3,666 is $3,666 more than $0.

What is your lesson here? My lesson is to become the house, because the house always wins.
