I would trade in 5 years of my life. 150k would be good enough for me so I can live a good life with it and buy things I want but I'm not gonna spend it on stupid or unnecessary things
I'm assuming we are trading years taken off the end of our lives;
As of right now, I would take off one or 2. Pay off some debts and some child support, pad my savings, and start living a little more comfortably.. all that reduced stress would greatly improve my current quality of life.
