Ok, so I've been playing for almost 5 years, and I realized that everytime I play live (and i use a pick) my wrist wears out fast, and i screw up the rythem. I think the problem is I put both my middle and pointer finger on the pick, dont use my wrist enough, but rather my arm. My question is: Should I be holding the pick just between my pointer and thumb, so improve stamina and speed? please help!!
