What if you want to get more done this year than just 3 things? That's great. So do I. So then set goals on a quarterly basis, instead of an annual one. 3 priorities for the next 3 months. You finish those, you can add some more. If you don't finish them, you keep at it for the next batch of 3 months. I look at my year 13 weeks at a time. Control how much food you put on your plate, and you'll be surprised how much healthier you'll be.
You don't win by doing everything. You win by doing the right things well. And there are only a few right things.
Set fewer goals. Hit more targets.
