I used debuggers long ago, but I've found that I work just as well, if not better, without them. I have to actually understand the code, not just get to a certain point and see what the variables are. In the end, it means I know that section of code inside and out and can rewrite and/or refactor it as needed to solve the problem. It usually results in cleaner, more efficient code.
