For work I use a calendar (Outlook) as a todo list. A task gets added to a date and time in the future so I know I can't forget it. When the day comes, I either do the thing, or I postpone it to a later date. For clarity: I don't use the taskplanner, but add tasks as appointments in the calendar.

This solves, for me, the problem of picking the 'right' thing to do from my list. I just do the things for that day. Be flexible, when you have extra time you can pull things closer, when it's balls to the wall, just shift some tasks to a later date.

I've been doing this for about 25 years, it works for me, might work for others too.

edit: I don't do notes, as such. Never felt the need to write something down that I won't ever look at again anyway.
