One of the things that I still struggle with, years into the productivity space, is making my to-do list doable. I don't want to put each step to complete something on the list, because a) I don't need to be reminded that I need to fetch the stepladder when changing a light bulb, and b) the list gets far too long the more granular I go.
On the other hand, if the tasks are too big, then I can't get them done in a small amount of time.

I've been a fan of Mark Forster for a long time now. Besides being an eloquent writer, he takes it upon himself to innovate new systems and then try them out in his own life.
