I find that my life improves a lot when I shrink the time horizon. Instead of worrying about long-term goals, I just focus on the next hour. Do one thing that moves me forward. One closed loop. One workout. One hard conversation. One whatever. Thinking about how to build a successful life is daunting. How can you have a successful day? How can you win this hour? Do that. Then do it again. Momentum is a byproduct of movement.
