I shall, but I also want to play U2 and anyway it's pretty unlikely that i'm going to write anything better than the Edge
And basically everyone emulates their guitar heroes very few guitarists I know actually try to make their own music, that's a bit advanced

Ahh. I've been playing for about 3 years now, I did try my best to emulate Edge for the longest time, so you're right there. Eventually though, I started getting bored of playing someone elses music. I don't know how tribute guys do it, but I mean, take Edge's advice. I can't remember which article I read where he said this (i think it might've been the 10 ways to play like Edge), but the 10th way, or 1st, or whichever one came last, was DON'T play like Edge. Edge's entire message when it comes to gutiar playing is "go out and re-invent the instrument, don't do what someone else has done, create something new".
After I read that article, or interview, or whatever, I really took time to think about where I stood as a guitar player. I could play U2, U2, and more U2. I literally pictured myself meeting Edge, and wondered what he'd say when all I could play was his songs. To be honest, he might be impressed by the dedication, but not by my creativity whatsoever. I couldn't play much of anything else. At the time I didn't feel like learning anyone elses music, I was still too interested in U2's, so I decided to start writing my own. It's no easy task, probably everyday i come up with a new melody or riff, or chord progression I think I can write a song of, (not to sound arrogant, but it's not hard) but they rarely become full songs. I've probably been writing my own music for about a year now, and I'm proud of about 10 songs I've written. Writing your own music makes you evolve as a guitar player. It makes you explore new techniques to enhance your writing, and it also lets you be more creative then say, playing only U2. I'm not saying start now, if you want to play U2 play U2, that's what I did, it helped me build my playing and my knowledge of the instrument, and my knowledge of music in general. But eventually, you will probably get bored of doing that. Either move on, or start writing, because you'll never evolve as a player if you only play U2.
I'm just saying, you made it seem like you'll never take a crack at writing, but that's where music becomes really fun and rewarding! Sorry if I seemed like I was telling you off for playing U2 (or others) or something like that, it wasn't what I was trying to do at all. 
(:$ ). It's a great fun indeed.
