Have you thought about doing some smaller projects? I started a couple of months ago and I really like completing a project. The largerst thing I've made is a poncho for myself. (finished yesterday!!) I started crocheting an afgan last year and I never finished it. It was just to big and to long of a project to keep my attention. So far with knitting I've done a scarf, couple of pairs of socks, a purse, and poncho. I learned different things from all these projects. I try to learn 1 or 2 new things per project. After the newness wears off I may want to try something larger.
I don't understand everything on here either but I've found that I understand things better as I work. If someone would have tried to explain how to knit a sock without me working on it I would never have understood what they were talking about.
