I’ve found 30 minutes works just fine for programming as well as the more mundane tasks. Primarily because it’s not always 30 minutes, that’s just the minimum I can get away with on a regular cadence.

Then a spare weekend will finally come around and I’ll have made enough progress that I want to spend an hour, or three, on the project.

The purpose is to make progress however you can. This is also why my other points are so important: work on something that will directly benefit you (scratch your own itch) and have a clear objective outlined.
