Actually, most of my business is
not actually around that stuff. It's the shingle I hang, but I worked as a wage slave for most of my life. I'm now at the point where, if someone wants to work with me, I will do so, on my own terms, and try to make that clear, so I don't really get a whole lot of approaches (not surprising. I'm not complaining).
I am currently keeping my dance card [very] full, working for nothing, on stuff that interests me. I would have been happy as hell to work for others at a fraction of the cost of many, as I don't especially care about the money, as I do about the working environment and project goals.
I like working. I really do. I just get quite tired of having my work destroyed and hamstrung by others[0], so I'm actually living the dream, these days.
Recruiters..love me...until they find out that I'm not young. Then, the call gets interrupted, and I never hear from them again. I've taken to just making sure everyone knows my age up front, so we don't waste each others' time. That seems to have stopped a lot of those types of contacts.
And I have not "always been on my own," as I worked on huge teams, consisting of people all over the world, but I haven't found any team that was willing to cut me much slack. I've always worked in environments where I was expected to hold up my end of things without a need for much extra support. No safety net. The trapeze is all mine.
