1. Get as much sleep as you can. Consistently. Yes, it's counter-intuitive. Yes, you'll have fewer waking hours. But those few hours will be many times more productive and joyful.
2. Drink more water and eat fresh food. Eat less than you normally do.
3. Get plenty of fresh air and sunlight.
4. Get a good amount of physical activity throughout the day (exercise, walks, whatever works for you)
5. Get plenty of vacation time during the year. Do not do ANY work during your vacation time - focus on enjoying yourself. (Ideally, 1/3 of the year should be spent on vacation time)
6. Make a list of the 20 most important things you want to accomplish (near-term). Sort the list so that at the top you have the things that you feel most passionate about. Keep the top 2 items and scratch everything else (I don't mean de-prioritize - I mean scratch it / drop it / burn it / forget it / it ain't happening.)
7. Focus all of your time and attention on doing those things that are most exciting TO YOU personally. Whether those things have any utility to anyone other than you is irrelevant. You come first.
8. If there is anything else that still absolutely needs to be done - find a way to delegate it to someone who's good at that stuff.
9. You will be unstoppable.
