Speed versus Quality:

"There’s nothing wrong with speed. All things being equal, it can’t hurt to finish a task faster, so long as you don’t get obsessed about such ends. But it’s not lack of speed that’s holding us back from producing more impactful results. The real enemy in modern knowledge work is the overwhelming quantity of obligations, tasks, and projects that we’re managing at any one time.

Each thing we agree to do brings with it a hidden “tax” of overhead needed to maintain it ..."

"In [a] distracted state, it’s difficult to produce quality and important work at any reasonable rate. The problem, in other words, is not lack of speed but instead lack of (schedule) space. What we need to produce at the highest level is not more powerful tools, but instead freedom from an overcrowded plate."
