I played trumpet from age 9-14 in band and orchestra, but I lost interest and quit. I've played guitar for the last 21 years. I never lose interest in it.
One great thing about the guitar is that you have access to the entire range of the instrument immediately. There are no pesky strokes or popped blood vessels in the eye to deal with. And, particularly in the case of the electric, the guitar is so expressive. I think that the electric guitar is the modern day equivalent to the violin in terms of how expressive it is. It's easy to change the timbre of the electric, too.
