Never let good be good enough

This was a catchphrase on a training video for a job I had many moons ago. A coworker and I had a running joke about it for a while because we both thought it was completely ridiculous, but in a weird way it’s kind of stuck with me. Could it be my perfectionist side coming out? Yes, of course. I always have this need to be “perfect” and make people proud, though often it feels as though nothing I do will ever be “good enough” so… is it true that I can never let good be good enough?
