Do not confuse inactivity with lack of progress in a changing environment.

In a changing environment, the situation develops whether or not you are acting on it. Time passing can improve your position, clarify the facts, or remove obstacles without any input from you. Judging your progress only by your own visible activity misses all of that.

Ask whether the thing you are waiting on is actually moving on its own. If it is, your stillness is not stagnation. Reserve your energy for the moment when your action will matter.
