One useful trick for better productivity is to avoid setting goals to be completed today or this week or this month. Instead, focus on getting a little bit better than you were yesterday. Maybe that means you do one more task, avoid one more distraction, answer one more email, and so on.
Focus on you, not the task. It’s a cliche, but the best stuff comes when you focus on the journey, not the destination.
Focusing on the journey makes the destination better than you could imagine.
