Showing Up
Showing up says nothing about the length, or intensity, or the result. Showing up also has nothing to do with liking it or disliking it.
Showing up is showing up. Being present is the first step to being professional. You might not want to do it, but because you are a professional, you do.
Being professional doesn't just mean you're good at something. Being a professional means you got good at something because you showed up day in and day out, and still continue to show up.
