Heh, I get your drift Mark. Since college, whenever I had access to a guitar (roommate one year, then my wife had one lying around that she hadn't played for years) I'd follow the same formula:
1.) Pick up guitar
2.) Quickly build my capabilities up to the last time I picked up guitar.
3.) Hit "the wall" (learning new stuff above and beyond what was I had learned last time) and get discouraged
4.) Put guitar down for a couple years.

I think the frustration was compounded by the fact that, being a drummer since 5th grade, I somehow in my mind expected to be able to get as good at guitar as I was at drums in no time flat, even though one does not relate at all to the other. But it, in effect, took until I was playing with some regularity (at church) that I started practicing with some regularity. My abilities have developed slowly, but I still don't push myself enough, as is evident by the calluses that disappear as soon as they develop...
