Somewhat tempted to learn a new instrument

I played the alto saxophone for about four years in middle school and part of high school, but I eventually gave it up due to lack of interest. I still have my saxophone and as much as I enjoy it's sound it still doesn't really interest me as something that I would ever want to play again. The sounds are wonderful, but playing anything with a reed doesn't really appeal to me after having done so for a while, it's a lot of work and playing with your mouth can be quite cumbersome at times. After seeing The Wind Rises about a month ago my interest in stringed instruments started going up. I've always liked them, but something about the main theme from the film really got me listening to a lot of stringed music of that nature. I've thought about maybe picking up the violin or viola, but I don't want to jump on that impulse in case it's just kind of a passing curiosity. I have had flitting thoughts of playing something new for a while now, but those just kind of come and go with my mood. If I did pick up something new, I want to be sure I'd stick to it. Not sure where I was going with this, just something to think about I suppose.
