High-value activities
I have an app that asks me 'what's the most important thing you need to do today?', everyday.
I seldom give the right answer.
Not because I can't bring to mind the action(s) I can take that'll give me the highest return.
But because doing the tertiary things--the things that are as easy to do as they are to think of--is what I choose to get done.
Alas. Doing what's difficult is valuable. Which is precisely why hard-to-do activities are worth prioritizing from the start.
