Fighting Temptation

I've been reading about how temptation is the tool that tries to keep us away from knowing God and at the same time an opportunity to show how much we love him by resisting it. One thing I started to noticing ever since then is how often I am barraged by temptation in the span of a day, it's uncanny. What makes matters worse is how often I give into it even, both consiously and unconciously.

I've decided to take a stand against one of the things I tend to succumb to the most, buying junk food. Also, since I full well know that I tend to have very will power to do this on my own, I'm using a little tactic that I learned while I was in Cuba (Which I will write about later on). It's simple, If I break any of the following conditions for the month of March I pay two of my housemates a dollar each.

Here's the Conditions:

No food/snacks from a vending machine.
No snacks from any convienience stores between my house and on campus.
I get two poutine credits and two pizza credits for the month. (I already used one..dang)
Nothing from the chip truck on campus.

My reasoning for all this is that, I always use the excuse that it isn't a lot of money I'm spending to buy that stuff. It's a bit of an spiritual/economics game, resist temptation by pricing myself out of that market. At the end of this I really want to be able to say "This is what I sacrificed for God." I'll need every ounce of strength to do so, because I'm already finding that temptation is one formidable foe.
