I only wish I had discovered the wonders of VCS earlier... I just started a new project, hosted on Google Code, using Git for the source code repository. This makes my life MUCH easier. Reverting back to a older version is far easier to do now, should I ever need to do that. Also, I can easily see how my code has changed over time. I've only made 2 commits so far, one initial and one to fix a bug. I'm already liking Git, now that I have figured out how to use it.
