Why do targets I can't control wear me down?

You wake up owing a number to someone else. The call, the no, the rejection — you feel all of it. But the number that decides whether today was 'good' depends on luck, timing, and other people's moods. You did not choose that scoreboard. Yet you let it choose your mood. The tiredness is not from the work itself. It is from measuring yourself by something you cannot fully steer. Say no to a hundred people in a day, and if you judge yourself by their answers, you will end the day empty, no matter how well you spoke. Here is the plain fact: you control the call, not the outcome. Keep those two separate, and the exhaustion changes shape. It becomes effort, which you can manage, instead of fear, which you cannot.
