If you suddenly had 3k/year or 3k/month extra, what would you do with it?

Payoff my student loans a helluva lot faster, that's for sure... then start on the mortgage.

With 3k/month, I'd probably go off the grid and live somewhere remote and scenic.

Realize I could get by with working a bit less. Time is the ultimate luxury good. When you can maximize that you are laughing.

Would probably disappear with other income increases I've had

Pay for college
