Yes, making lists is a form of exercise – mental/brain and physical.
For me, rarely if ever do I follow the list. It’s the making of one that motivates me to get going again. It doesn’t matter at what. One thing leads to another thing is the continuing motivating force that leads to success in getting things done – maybe not in the order I listed them and maybe much of it wasn’t even on the list, but it all eventually gets done – and then some.
