As far as I know, fun is what it's all about :) if it stops being fun you're taking it too serious.

I play for pleasure, obviously there in the far recesses of my mind the inner rock star is telling me I should practice more and get on stage ;)

I play when I can, which is most days, and I make the effort to do some scales and fit in a few riffs that I like. It's fun and I think thats how it should be :D
