Natasha the Nomad has a post about prioritizing the “one thing” that has to be finished today, even if everything else slips:
When I wake up (or the night before), I think “What is the one thing that I can do today to feel like I had a successful day, even If I nothing else gets done today”. No matter what, I end up getting that one thing done.
I find this kind of approach really useful. Saying you’re only going to finish one thing is admitting the reality that for many days, if you’re unfocused or juggling too many tasks, there’s a lot of “work” but nothing gets done. When I work out of the house in the morning with my iPad Pro, my goal is equally simple: publish a single blog post. If I can take care of email, edit other draft posts, work on planning notes for a project, etc. — that’s great too.
