My brother started guitar and I followed not too long after. He quit but I didn't. I've always played alone except for a small band once but never performed on stage.
I got hooked on the guitar because when I played, I was in a world of my own. I was really teased at school and the guitar was for me a savior. It brought me joy when there's wasn't any. That's why I got hooked, the joy of playing.
The band that got me started was Metallica, then I turned to Yngwie Malmsteen, Satriana and Troy Stetina. Now speed doesn't impress me so I turn to guitarists like Jeff healy, SRV and other bluesman for new challenges. I'm slowly discovering the less is more approach.
I'm rediscovering the guitar. That's the greatest thing with an instrument. When you think you've seen it all, it comes out with something new everytime.
