1. Make the action small and sustainable
2. Find a strong purpose, as timeless as possible
3. Get a cohort together that shares the purpose
4. Reduce as much friction as possible
5. Know that some goals will have a shelf-life; it's alright to bid them good-bye.
6. Daily is better than every other day/weekly
7. Find a channel (for reminding each other, conversing) that works for you
8. Positive peer pressure works; find people/causes you can't let down
9. Celebrate even the smallest of milestones
10. A habit is most vulnerable at the beginning, during vacations, when something else puts you in flow, and after a streak has just broken.
