Thanks for all the replies. They've been most helpful. I'll try to make my practicing a bit less based on what I WANT to learn, and more based on the things I actually NEED to improve (such as scales and changing between chords in time). Until I improve those simple things, I guess I shouldn't even begin trying to compare myself with better musicians, and instead just compare myself to where I was when I first picked up the Guitar...

With that said, I'll just go give it a shot right away!
