I'm fortunate, in that I was able to save up enough of a modest nest egg, so that it doesn't matter.
I have skills that could make a lot of money. The problem is the way that the folks that pay me, treat me, and my work.
People seem to take the fact that they pay money, to be carte blanche to treat the people they pay, like garbage.
When I was younger, I could eat that s**t, but as I got older, I got crankier.
Nowadays, I do very good work, for free, for folks that couldn't afford me. They can be a pain, but I can also walk away (or threaten to), and we can usually work through the rough bits.
