If you control when the reboot happens, you will plan something for it. What I think is absolutely necessary in our lives, even for those at Google, is a significant amount of unplanned events, unexpected experiences, or any other occasion to prove to yourself, to feel deeply inside, that you are not a robot.

Maybe it is personal, maybe it is cultural, or maybe it isn't: I don't like (an understatement) fully planned trips where you are told "the 8th of July at 10:45, you will get an artistic ecstasy in fron of the Taj-Mahal, the 9th [...]". I won't work on anything that has no risk to be hard to control and nothing unexpected can happen. I don't mind if my PC has to be off for 10 minutes.

I work as a teacher. I can plan lessons as much as I like (and today I'm planning for an observed lesson next week or week after) but I can tell you, something unexpected always happens in the actual lesson. The plan lasts 20 minutes if that. The rest is 'reflection in action' to quote Schon.
