I would pay off our house and all of our debts, give my parents enough to pay off the little debt they had and for them to go on some nice trips.

Buy a house for my older son and set some aside for my younger son.

I would put the rest in diversified investments and keep working and keep putting money out of my paycheck aside for retirement.

I am a developer and like what I do for a living. My wife would probably still work for the health benefits but she already doesn't work during the summer, she might go half time.

We would probably take nicer vacations and have a little bit better cars but I don't see our lifestyle changing drastically.

And no, we are by no means "rich" but we earn a decent enough income that more money wouldn't affect our lifestyle too much.
