m-altruism:

1. Don’t overthink. Too much thinking often results in getting stuck, in going in circles. Some thinking is good — it’s good to have a clear picture of where you’re going or why you’re doing this — but don’t get stuck thinking. Just do.
2. Just start. All the planning in the world will get you nowhere. You need to take that first step, no matter how small or how shaky. My rule for motivating myself to run is: Just lace up your shoes and get out the door. The rest takes care of itself.
3. Forget perfection. Perfectionism is the enemy of action. Kill it, immediately. You can’t let perfect stop you from doing. You can turn a bad draft into a good one, but you can’t turn no draft into a good draft. So get going.
4. Don’t mistake motion for action. A common mistake. A fury of activity doesn’t mean you’re doing anything. When you find yourself moving too quickly, doing too many things at once, this is a good reminder to stop. Slow down. Focus.
5. Focus on the important actions. Clear the distractions. Pick the one most important thing you must do today, and focus on that. Exclusively. When you’re done with that, repeat the process.
