Being productive isn't just about quantity. And it's not just about quality either. It's about getting the most important, impactful things done efficiently, and to a high degree of quality, without getting hung up on perfection. This last part is especially tough for many of us.
Like most things in life, there are two ends of the spectrum. On one end you've got no structure. You bounce from task to task and back again, free-flowing and aimless. Constantly jumping between mental states, conversations, browser tabs, etc.
