Doing creative work can be embarrassing: putting yourself out there for all to see, waiting to see if anyone responds, all the while unsure which scenario you fear more - someone actually seeing it and responding or no one seeing it. Both sound terrible in the beginning. 

I'm sure there are things I probably never published because I felt embarrassed, or maybe things I never said. I'm sure there are projects and ideas I've never shared because I was embarrassed. Somehow I came to think that embarrassment about something before sharing it was a sure sign that the thing would indeed be embarrassing (i.e. a total failure).
