4 years and running.
14 is when I picked up Maya, used it for 2 years and now I'm 18 with Blender.
I've got lots of time into 3D, tons of tests, tons of mini projects. I love working with 3D.
It's very very difficult to get composting, modeling, animation, physics, particals (biods, keyed, static for fur), materials, textures, lighting and the like to flow together for say a still scene.
I've yet to finish a piece of work that I'd proudly show(Yeah I've stuff but a finished scene or animation),
hopefully that will chnage with the current one I'm working on.
