Only thing you have to be careful with this method is that you prioritise some stuff you actually want to do regularly! I did something along these lines but obviously having fun was “less important” on this scale than getting work done so I got into a mess where I didn’t know what I found fun anymore and couldn’t relax at all.

I find it easier to select 3 things that I must get done that day (and all 3 can be fun things if that is the kind of day you are having) and once I’ve done those I can relax a bit.
