If you take every job you are offered, you will not have the time and mental space to do the work you need to advance your career. It becomes all about the money, or maybe specifically, your fear of not having enough. The work, and your career, will suffer.
This is a very hard lesson, especially if you have just come off some lean times. And it often means you need to walk a tightrope. That’s OK.
I sometimes fail on this one, but less and less often as I advance. The road behind me is littered with the corpses of directors who didn’t ever learn this lesson.
