i was wondering how you all hold your picks, as i hold mine on the second joint of the pointer finger, which i found out is not a "correct" way to hold a pick in a book i read.

Have ure index finger at a right angle then keep the pick in place by your thumb which will go across the bottom part of the right angle

Really it should be whatever feels comfortable and doesn't hurt or sound bad, so you can use whatever you like.
