What are the few things?
It’s possible to be invested in so many different legitimately useful ideas & projects that you are unable to pursue any of them to completion.
I suspect that the reason why some people are better at getting important work done isn’t that they have fewer things to do, but more due to the fact that they‘ve made a firm habit out of only ever focusing on a few things and not moving on to something else until they are complete.
It’s a good habit to have.
If you feel like you’ve got a lot going on, the most prudent decision to make is what few things you want to see to completion first.
