Neither is necessarily better than the other, and the best people can do both. Doing both at the same time, however is like trying to play ping-pong and philosophize. It’s just not going to work.
To tell which state you’re in, ask yourself “Am I in the middle of shit, or am I above it?” If you’re in the middle of shit, you’re being reactionary. You need to be in the middle in order to commandeer the ship at breakneck speed, handling the operational details. On the other hand, this sort of short-sighted view won’t help you decide where the ship should be sailing.
Learn to recognize the two as separate, but equally powerful. Understand how to pick one mode or another, and only do one at a time. Don’t let your reactionary side steal all of the time away from your visionary side. There is always time for big ideas.
