I'll use music for an example. You practice and practice and it seems that your stuck playng the same licks over and over again. Then one day something magic pops out and you have jump the the next level. Everything is fresh and anew, for awhile, then back to the same monotony(sp?). In any artistic endevour, it's the same thing. Just keep at it and sooner or later you Will jump to the next level. Trust me, after playing guitar for over 35 years, it's normal.
