It was a challenge, but not extremely hard! Once I get an idea in my head, it is hard to stop me...luckily, the idea was that I was determined to pay off that credit card! Mostly because I was mad at myself for letting it accumulate there until the interest kicked in.
Finding Money Mustache helped me a whole lot-you all showed me clearly the areas that I was wasting money on, and now I am on my way to a very mustachian lifestyle, hopefully one with no student loans very soon on the horizon, and early retirement not far after that!
