Throught high school it was a way of not letting things get to me. I was teased a lot and didn't have a lot of friends so I needed something to help me in rough times.
The guitar was great, it helped me gain self esteem. And Let me focus on something good (music) instead of what was going in my life.
Now I do it for fun. I enjoy playing even it's only 15 minutes a day. I have enough skill to be able to create and jam by myself.
All those years of practice paid off in the end :)
