Electric metal blues

Bah! I had a blast on guitar tonight but couldnt come up with anything worthwhile, same old stuff again and again!

I know I mentioned creativity last time but this is one almighty rut.  It seems like im bored of playing all the stuff that im good at, the only stuff I enjoy is Hendrix blues stuff and im not so good at that.  My natural style or learned style is metal and grunge although if I just pick up a guitar and play it come out like 90's thrash metal rather than grunge.  Even the lead stuff that I normally get a kick out of playing is tiresome.  I look forward to picking up a guitar and having a jam but after every session I feel fed up and frustrated, dont know if I can bring myself to learn a whole new style, not with my attention span...
