I can't strum up very well. My pick always get caught on the way up. Am I not relaxed enough? Can someone give me some advice on how to properly up strum? Thanks in advance guys!
It is only with the heart that one can see rightly; what is essential is invisible to the eye.

look at videos of people playing guitar. you can try holding your pic at a slight angle (turning it slightly while keeping it perpendicular to the guitar) so that the curved edge will slide over the string instead of hitting it flat on.also, try tilting your pick/hand up on the up strum a little so that it wont get caught.

it will become natural feeling soon enough, just takes practice.
