I compare it to day trading, where you always close out your position at the end of the day, and never leave anything running overnight. "Restart kernel and run all" when I finish a lab session. Assume that I might not come back to it for a long time, and that it won't be fresh in my mind.

It's harder when some of your cells took hours to execute, which mine don't. Then I think you should be using data files.

The tools that fix this problem seem to evoke "the cure is worse than the disease." At this point, basic Jupyter notebooks are by far the most reproducible way I've ever worked.
