I looked and i really didnt see a thread about this but if there is one then I'm sorry! 
But i need help >>>
I've been trying to play a lot of stuff like older metallica(mainly off of "kill 'em all") and stuff of the sort, even some faster punk, but my hand will either just not pluck that fast or it will like tense up and slow down. I know I'm supposed to be relaxed and not stress my hand too much, but even if I do that I'm still not fast enough.
Any exercises or advice would be awesome. Thanks
Oh, and I dont feel like using a pick (not too good with those haha) and I feel like sticking with two fingers
