I retired in my late 30s and had kids. So I’m a full time parent as is my partner. I guess that’s my revealed choice for what my ideal job would be? Sometimes I’m not completely happy with my choice, but mostly I am.

If I had more time, or more energy, I’d program for fun more often.

I don’t especially believe in “changing the world.” Not that you can’t (though really, you can’t, to 3 sig figs) just I don’t care to.
