I want out of architecture. My heart was never really in it, & yet 19 years has gone by since I started down that path, so I have been in it long enough. Aside from choosing what to do next, I need to make some decisions. Anyone have experience with changing careers?

I'm leaning toward prototyping/robotics/fabrication. I will definitely be returning to school for a few courses - I'd rather not commit to another degree though. With that, I think it is time to dive into Solidworks so I can get away from Autodesk. I have no business experience but creating a company may also be in my future. Beyond that, I am not real sure what focused direction to aim for.

Does anyone have any thoughts or opinions or experiences about this type of step?
