Motivation is a whimsical thing.

  The fantastic element that explains the appeal of games to many developers is neither the fire-breathing monsters nor the milky-skinned, semi-clad sirens; it is the experience of carrying out a task from start to finish without any change in the user requirements.

(a) make sure that the goals are set to stone and crystal clear

(b) the team can do their work without any unnecessary distractions

It can be really hard. And it can very ungrateful. I aim to be a nightwatchman, and I'm really proud of myself when the team thinks I'm getting paid for nothing. The bigger the structure the bigger the drama and I don't want them to be any part of it.

Meanwhile I struggle with stakeholders who are like "c'mon, you already build the skyscraper, we just want you to move the parking lot from the underground to second story, how hard can it be, you have all the parts in place, just move them around".
