you cant push yourself too far. play whatever you want. thats how I got good. I started working on the trooper by Iron maiden and i can play it easy now.
Yeah, I think so. Unless of course you CAN play it, it's a matter of knowing your abilties and limits.

Don't get frustrated if you can't play something at first, play some other stuff for a while and come back when you feel your ready.
NO i know the whole song, i can play with the real song itself. I just make some mistakes on Dave Murray's solo(1st Solo). The part where it says to use the Whammy bar after that. Their is some stretching. This song actually helped me use my pinky in solo'ing a lot more. i guess u guys are right, never to much to push ur self.! thanks again
