I'd like to contract all (first-line) support out to some company if I can afford it and as spill-over support for those periods I need it most. That would be enough: it's a non-tailored services business. It could be worse. I might want/need to isolate when depressed, but I can give support.

There are not that many subcontractors that I need help with that.

People who wanna sell me stuff can wait. Let them try another time.

I know my weaknesses (which are plentiful) rather well, I hope, and I agree it's important to know them. I think I have to learn an awful lot more, also about my BP and my personality. Not coincidentally, I can work on that as part of day-to-day work (some periods more than others). I am a perfectionist but not a control freak. Maybe a control freak, but not in an ad-hoc way.

A family member to support me might not be such a bad idea after all. Quite a few relatives have businesses of their own. Most of my friends are too much like me. I just need someone to keep things going, someone good with (some) routine.
