I've been training in martial arts for the last 14 years, although with varying intensity: I've had months where I trained five days a week and I've had six-month breaks. 1-2 times a week probably was the schedule I sustained for the longest periods.
I made it to the green belt in Tae Kwon Do and then switched to Shaolin Kung Fu, because I thought it was much more interesting, with all the weapons and a lot more variety in style.
I like about Kung Fu (at least the way it's taught to me) that it has such a rich variety of styles and so many hints at its very long tradition. There's a bunch of weapons, there's spiritual elements to it, playful and artistic ones (like the dragon dance), and even downright dirty streetfighting stuff. You can tell that it's a mashup created by generations of all sorts of people, soldiers, monks, artists etc., under all kinds of circumstances. It's also the most humorous martial art I've encountered, and has almost no formalisms, which is a great counterbalance to its training regime that can sometimes border on abuse.
