As I get further into the home building process, I'm confronted with a lot of "might as well" temptations. You know — I might as well add extra square footage here, I might as well install more lighting there, I might as well finish the basement now instead of waiting a few years.

Before I know it, I've might as welled myself right over my budget.

College presents you with a lot of "might as well" temptations, too — ones that you might be paying off for a long, long time, if you're not careful. Here are a few examples:

Might as well (MAW): I don't need all of these student loans, but they've been offered to me, so I might as well take them.

Why you should resist (WYSR): If you don't need the money to pay for school right this minute, don't take the loan. You're going to have to pay it back, with interest. In most cases, the interest starts accruing as soon as the loan is disbursed. Why pay interest on money you don't need yet?

MAW: I've got leftover financial aid money — I might as well use it to buy an Xbox .

WYSR: If you have leftover financial aid money — and really, you shouldn't, if you look at the previous WYSR — throw it at next semester's tuition, or use it to pay for living expenses. An Xbox does not count as a living expense. Besides, shouldn't you be studying? If you really need to play Halo  or Guitar Hero  (and sometimes you do — it is good stress relief), just head over to your friends' place and take advantage of their poor financial decision making.

MAW: Even though I'm financing my college education with loans, I might as well skip my Economics class. It's boring, and I'm tired!

WYSR: Think about what your classes cost per credit hour, figuring in books and other materials. Then think about the interest rate on your student loans. There's some sort of mathy economics formula for figuring out exactly what skipping class costs, but you don't know what it is because you skipped Economics! Bottom line: time is money. Get your money's worth by getting out of bed and going to class.

Feel motivated to fight off the "might as wells" now? I sure do. I'm off to resist the temptation of granite countertops.
