Here's one thing I've always found reassuring: When I look at code I wrote a year or two ago, I invariably find a lot of things I could have done better that I didn't know of back then. This generally tells me that I have improved and I am looking at the code with a greater set of evaluation tools and/or a better thought process. Where I would get scared is if I looked at code that was 2 years old and I couldn't distinguish it from code I would write today. That to me would be a clear sign that I am not improving.
