5K could do a lot around here!
I would put 1500 towards an old credit card debt instead of fighting for a smaller settlement.
Then, I would fund a few sinking funds: 150 Car Registration, 250 Car insurance and 200 each to the two school funds, christmas fund and a vacation fund.
That would leave 2300. I recently found out I need 3200 in dental work (after insurance), so the last 2300 would go towards that. I could get a lot of work done really quickly instead of having to save up and wait!
