Even when I know that I should not finish something, there is still a surprisingly robust mental barrier that holds me back from it. The solution that works for me is the making a 'Low priority' folder to put those projects I know I don't need to finish. Moving them out of my active workspace feels great, and the 'low priority' means its non-committal to completely abandoning them (although in practice 99.9% of the time, that exactly what the result is).
This is a mental trick I play on myself that I know that I am doing, but somehow its works anyway.
I really need to do this!
You reminded me of the early days at inscribe.ai where we just had an Asana board with red, orange, and yellow tags meaning high, mid, and low importance, and after completing an important one I'd treat myself to a few unimportant ones. I'm not sure I ever did anything in the middle!
