Hey financial planners!

So, even though I realize that I haven't paid off my last gear purchase or spent my christmas money on, say, a flight to go visit friends cross country, it still seems like I'm doing a pretty good job of living within or just beneath my means. Would a better way to put extra money to use be:

a) buy myself more presents!
b) start putting some money into my pathetic little savings account
c) make larger monthly student loan payments
d) look into those weird things on the car before they get weirder

or some combination of a few/all of these?
