For me, this is how it started. I was sitting around with a dozen or so friends and one of them had a guitar and he was trying to play a Rolling Stones song. Everyone was impressed, everyone but me. I was like, what the fuck was that? That did not sound like the Stones at all. So I said so. They said they'd like to see me do better to which I took the guitar and proceeded to play "Rock & Roll Hoochie Coo" by Rick Derringer. The next day I traded my Zappa album collection for a Les Paul copy and I never stopped. At 18, I left Connecticut for Hollywood, CA and a G.I.T. education.
The only way to get better is to go futher than everyone else, prctice actually starts after your done practicing. That is something you have to push yourself into, practicing after band practice. When you think your done, play for another 3 hours. Warm up for 2 hours before you perform, just like Eddie or Zakk do, or do like Dime bag or Jimi did, never take the guitar off your shoulder. Jimmy Page is considered a sloppy player, he played his guitar for 12-18 hours a day to get that sloppy! EVH is up all night long playing his guitar, according to Sammy. "Finish What You Started" was written and recorded at 4 a.m. To hear Sammy tell it, you can understand the OCD that EVH had for the guitar. When I was at GIT, I lived with my guitar 24/7 and only stopped playing to sleep and shower, I was known for it.
When I bought a second Strat, a '63, I built a wall to hide my '55 in. I used to carry a MIM Strat & boss micro cube with me but now I have a beat-up Taylor 314 acoustic that comes with me everywhere.
I am much better today than I was last year. Oh, and I just got an email saying my new guitar is arriving today, another Les Paul!
