Playing with the Time Management Matrix in my #BuJo but the limiting resource isn't time, it's #spoons, so it's actually the Spoon Management Matrix and in addition to (externally) important and/or urgent, has a third dichotomy: (internally) nourishing/relaxing/stress relieving. The rules about prioritising important and urgent things holds, but you also mix in relaxing things as needed.

Just started applying this to email with labels :D
