Started dabbling in Linux some 15+ years ago, dualbooting with windows XP. Tried bunch of different distros - suse, Slackware, RedHat (pre-enterprise) etc. Didn't really understand it and kept going back to windows. A classmate had told me Gentoo was good for learning Linux. So once I was trying to shrink my windows partition to make space for another dualboot experiment, and in the process borked my partitions. They were probably recoverable, but I got furious, ragequit windows and installed gentoo on the whole disk and used it as my daily. That helped me learn.
