And one interpretation of the other expression is that much of the time we put things off because we can only do them well. So it is best to have a go and do it badly than never try.

Artists talk a lot about the "right to fail" - sometimes it is only some time after you have produced something that you know if it has been a success or not. Every year, much to the recipient's surprise, award ceremonies such as the Oscars bring to our attention people who have become an "overnight success". I remember several older (and a few younger) actors who were amused by this label.
