What are your opinions?

I have a couple things going on over here and I think I've found a solution to one of them. I have difficulty working in the common job market due to a few physical disabilities, and now old age is starting to have an affect on what I can and can't do. It dawned on me earlier this evening that if I can't find a suitable job to fit in to, why not create my own job or vocation? I have one interest that absolutely fits this criteria.
