Started F1 six weeks ago and about 60% completed. I have consciously paced myself as I know from experience that I am a slow learner. Enjoying it very much and making real progress.
Have taken Lisa's advice (and of others): leave the guitar out so you walk past it daily and practice regularly rather than binge practice. A guy on You-tube recommended commiting to only 5 mins each day - then you won't get the guilts if that is all you can fit in, but generally you're 5 mins will always end up turning into 30 mins!
