Got let go a week after closing on a house. Learned the true value of hard work and loyalty, as my network shunned me and I stumbled around for a few years in a new career. Thankfully my wife's income let us run only a little in the red for a couple years until I could find my footing again.

Doing great now, but I'm never giving a job any more effort than I'm comfortable giving. I killed myself with crazy hours for 3 years and had nothing to show for it.
