Thanks Madage! You're right, my past history experience with credit cards is questionable...but I've found a great solution to this after reading this blog. I no longer carry my credit cards. If I don't have my credit cards in my wallet, then i can't use them to spend! I also keep a sticky notepad in my bathroom with my credit card debt number and sallie mae loan number on there. Every time I pay off my debt by some amount, I take off the top sticky note, and rewrite the lower number on the next note. This may seem silly, but seeing those loan amounts every morning, constantly reminds me to pay those off ASAP. It's also rewarding to see that number get lower and lower.
Still debating about signing up for another credit card. I know I can be responsible now, because I discovered and am reading every post on this article. Still have a lot to learn though and a long ways to go.
