One per day can be a serious grind. The art doesn't make itself. I know this all too well as I currently rush to finish something I've been working on. Some of the responsible and highest paid bloggers sometimes do one every two or three days just to be able to keep up with quality.
The thing you said about work you're not happy with... just know; it's never about what you think of your work. I learned this long ago. I produced what I thought was a piece of crap, I said it was a piece of crap, I pressed the post button... people came along and said, "Well, I like it." So now, I just like everything I do. If it's weird, I joke about it. Instead of acting like some big shot, I make fun of myself. Some artists can be their worst enemy. I just say relax, go with the flow. It's all good.
I get what you mean; showing substandard work just disheartens me at times.
It is better to think of each creation more as a child than a thing though; once you release it's on it's way you have to accept it as perfect as it is.
