Looking back at your old code

I just happened to look at some code I wrote in 2007 and haven't touched ever since. Now it seemed embarrassingly bad. That made me feel good; I've been programming since the early 90s, and apparently I'm still making measurable progress in such a short period.

Any similar experiences?

I usually rewrite old code if it can be useful, but sometimes that shit is so bad I can't do anything.
