I started playing electric bass at the age of 15, and got an acoustic guitar about 6 months later. I decided to major in music in college since that was literally the only thing I ever felt like spending my time on (excluding girls, since you can't major in that). I picked the bass as a primary instrument and for the next 12 years never had a "real job". Traveled the world, met tons of interesting people, got treated like a rock star, got really good at the bass, gained a ton of "domain expertise" in the music business, and generally had a whole heck of a lot of fun. I didn't even think to start programming until I was 30.

There is an entire world out there, and you likely have a whole lot of other talents that you don't even know about yet. My advice would be to make sure you take time to discover them too.
