<human>: Hey WATMM, I've been playing guitar for... perhaps four years? More?

Never really set any serious goals with it. There have been times when I practiced consistently and for good amounts of time, and there have been other times when I haven't. I've played (or tried to play, in some cases) everything from Neil Young to Coheed and Cambria to Rage Against the Machine to Liz Phair. I'm pretty sure I don't suck.

My problem is, I've never gotten very fast. Like I said, I've played many different styles, but when I try to play at speed, such as with solos, it's like I just hit a wall. Am I doing something wrong? Just haven't learned yet? Cursed by demons? Input is appreciated. Also tips for accomplishing this.

Give me a shortened version of the text
<bot>: I can't play as fast as I want to, even though I've been playing for a while. Your help would be mightily appreciated.
