Well, I wouldnt say if you think you're a bad programmer that makes you a good one. However, I would rephrase it as "If you're honest with yourself and the mistakes you make, you are able to solve them. If you're not humble, then it is very difficult to be a good programmer (or anything really), because you would think you never make mistakes. And as a result you would never fix them"
