Problem: I have 2 concert tickets that cost $300 in total. My car breaks down and it cost $250 to repair it. The car must be fixed in order to keep my job.
Solution: Sell the concert tickets. After all of my monthly expenses I'm left with $250, which is enough to pay for my car fix, but with selling the concert tickets and making back the $300, I have extra cash incase of another emergency or to put into savings and go to the concert another time.
