My strengths include spelling and knowing when to use your and when to use you're.
Guitar wise I'm decent at slow tasteful solos, rhythm playing*, using odd chords and can write a pretty good guitar part when the mood strikes.
Weaknesses include impatience, I can't seem to sit and learn a whole song properly, I learn the bulk and think 'that'll do!'. Oh and I suck at soloing fast, but I don't really wanna solo that fast so that doesn't bother me as much.
*exception when Afgahn Dave and me tried playing the Trooper, I fell flat one my arse that afternoon somehow.
