I value my free time far too much to work for a living. So your model is correct on that count. I had planned to be mostly unemployed with occasional freelance programming jobs, and generally keep costs down.

But then a couple years ago my hobby accidentally turned into a business, and it's doing well. "Accidentally" because it started with companies contacting me and saying "We know you're giving it away for free, but free isn't good enough for us. We want to buy a bunch of copies." And because my co-founder took charge of the negotiations and other non-programming bits, so it still feels like a hobby to me.

Both my non-motivation to work and my willingness to donate a large fraction of my income have a common cause, namely thinking of money in far-mode, i.e. not alieving The Unit of Caring on either side of the scale.
