A lot of people have never run straight Arch, or not for long. It’s been my personal experience with Arch that, if I don’t panic, read the Announcements & Forum (if necessary) for my problem, and then logically go about fixing the brokenness, things work out.
I’ve learned more from problem troubleshooting than I’d ever learn by re-installing. Mostly what I’ve learned is how to keep a good installation good, and therefore keep it up and running.
