That's the attitude I am trying to avoid these days. When I look at something that I want to rewrite I now ask the following questions, 1. Do I have sufficient tests and testing to do this without breaking things? 2. Do I want to want to rewrite because I cant be bothered understanding it? 3. Is there going to be any gain now or in the near future by rewriting it? 4. Will I be able to rewrite it sometime in the future as part of another piece of work which actually delivers value? Unless I come up with Yes, No, Yes, No I tend to leave it alone. There are other things of value I can do with my time. EDIT - Formatting...
