I am big into working on cars. It started as a hobby but it's something I am working on more as a career. I like fast cars, I am good at design, modification, etc... and it's that 'passion' of mine that will probably leave me with an aching back and an empty wallet later on in life.
Aside from that I have really been digging introspection and working on myself as a person. I have been a real asshole in the past and while there is some 'bad boy' charm to it I think I would rather breed good vibes among people over getting laid if I have to choose at this point in life.
