Luck? I'm not so sure...

So on two occasions..I've found money lying around in the hallways of my apt. The first time it was a 10 dollar bill. Today I found two 1 dollar bills. I can't seem to keep money I find...I've always been the type that works hard for the money I have, and I get great pleasure out of buying things with my own money which I worked hard to get. Finding money...is another story. People might call it luck...I can't seem to find a reason to use it. The last time I found the 10 dollar bill, I ended up giving it away to a friend. Now I'm sitting here with the two 1 dollar bills...what to do..
