Cut the list in half
If you have more than 10 things on your priority list, you probably won’t complete them. Cut the list in half. And for good measure, cut it in half again. Aggressively subtract. A former colleague famously set up a calendar event titled “Good Idea Cut Off Date” — his way of saying that he didn’t want to consider any other good ideas after that date. He wasn’t trying to stunt progress; he was ensuring that we stayed focused on our core mission and accomplished what we set out to do.
