I’m a fan of David Allen’s Getting Things Done. His book spawned an entire industry. It also causes a lot of stress.
A few years ago David was speaking at a conference and folks asked how he managed to get things done:
1) Nothing gets done until I process everything. No cheating.
2) When I have time, I process everything into a single “Trusted” place. Some folks use a journal. Others use software.
3) I review my potential work weekly and decide if I still need to do it.
Nothing added to your list is more important than tasks already there. Processing everything together will reveal the best path. Stay focused, my friend.
