How many of your play the guitar? And what does it do for you?

I wanted to find something for my 9 year old to have interest in other than gaming. So I got my first electric guitar out of the attic, restrung it and gave it to him. 1-1/2 years later, he takes lessons every week and it renewed my interest in playing (was in a Punk Band in my previous life) and we play together at least 4 times a week. His interest, for him, turned into a passion. He knows so many facts about the major guitar manufacturers, their current and past product lines, what's hot and what's not, etc...it also sparked something else for him. When he wanted a BC Rich Warlock guitar, we went on eBay and purchased everything separately. We found the body he wanted, the neck, pickups, even some of the skull bling. That turned into "Dad, why don't we start custom rebuilding these used guitars as a business and sell them at a profit". So today we have a part time business and he gets the profit after I get back my initial investment for each one.

So this has done a few things for me: it has given me an outlet to reduce my stress; it brings me closer to my son so we have something for just us to do; it allows me to teach my son at an early age how to run a business doing something he loves.

So, do you play and what does it do for you?
