Ask HN: Why does a busy man build a shed?
Building a shed is a finite process with known steps that produces a tangible result.  If you spend time on it, you will make forward progress and be able to see it.<p>If you are a knowledge worker, this is frequently lacking.  You might spend months or years working on something without knowing of you'll succeed.  You might get stuck (eg, debugging) and not be able to see any progress for long periods of time.  You might be blocked from making forward progress because you are waiting on other people.  And at the end of the day, what you accomplish might not be very visible or might end up being finished but useless.<p>So it's nice to do something where you feel like you actually did something.
