I think this is a pretty good philosophy not only for writing but also for life. Years ago when I was a reader for a production company in Hollywood, a few of us were talking about why so many of the scripts we were seeing were so bad.
One smart person in the group (not me) pointed out that most things in life are nowhere near perfect. He said, "Think about most meals. Most of your experiences with bureaucracy of any kind. Most of the pop music you hear. Most of the books in the bookshop. How many of them live up to your highest expectations?"
To which one might add, "How often do I live up to my own highest expectations?"
Generally we're doing the best we can, and it's not anywhere near perfect. Sometimes it takes a few tries to get it right, whether that's several drafts of a novel or screenplay or several attempts at finding the right person to spend our lives with.
To me, the "draft" approach is about doing it (whatever it is) as well as you can, accepting the fact that you'll get it wrong a fair share of the time, and paying attention so there's a chance of getting it closer to right the next time.
If that way of thinking might make you less hard on yourself and others, I invite you to adopt it and to share it.
Hmm, I just noticed the final quotation mark is missing on the graphic above. I think I'll leave it--it kind of proves my point.
