I can't imagine working on any personal project without git. How often have you been working on something for a while, noticed part of it that was working before was now broken and had no idea why. If you'd been making regular commits to git you could go through recent/pending changes and work out was was different trivially. Git is also incredibly simple on single person personal projects, just git init, git add, git commit and some way to view the history and pending changes (either the command line, or most editors have a built in viewer).
