If you draft a list of what is important and you end up with more than three items, that is just a to-do list.

You can focus on one item at any single time, and you can allow one or two more for when that single, most important one is giving you a break. That is it. Anything that you add on top of that is just confusion and distraction, sucking up energies and resources that you could otherwise invest delivering against what is important.

You pick the items on that list. But make it so they are no more than three.
