I'd eliminate useless debt first. Then I'd buy a couple of houses for my family to live in, if I didn't give it to them outright (mom and sis and sis-in-law only). New vehicles for the same people. I've already chosen charities I'd donate to, on a percentage basis, many local. I'd probably support my sister and help her to finish her degree, mom too if she wants.
Beyond making appropriate personal retirement and maintenance arrangements, yes, I'd quit my job, but I'd get into something else. I'd like to set up scholarship funds for college students and grant programs for theaters and the arts. I guess my job could be managing those things.
I'd probably buy us a large house where I could host folks easily, and hubby could have his wood-working shot of his dreams. I'd replace the 13-yr-old car with something similar (maybe an SUV hybrid, heh). We'd certainly travel a LOT.
And I'd host a helluva party. Kinda like the one this upcoming weekend--Corned beef and cabbage for all!
