I didn't have saving money as any sort of priority. Not even a paltry $5/week was put away. I spent it as fast as I made it. Then, like Britanica, I lost my job. Unemployment payments weren't enough to cover my bills and with no savings I was sinking fast. I ended up getting on the debt roller coaster by taking a cash advance from my two credit cards. Add that the the already large balances on the cards and even after I got another job it was all I could do to make the minimum payments on the cards.
On top of that, I didn't take it seriously enough to really scale back on my lifestyle. The debt piled up because I kept using the cards. "Oh this won't be a big deal, its only a $20 charge!" Those charges added up. The straw that broke the camels back was the month the minimum payments were more than I could make! I ate noodles, rice and beans, balonga sandwiches and not much else for 3 weeks, to squeeze in making a payment before the late grace period!
After that I cut up my cards, and started looking for help online. I found this forum and some blogs after a while, after I had already started my road to getting out of debt, and they've been a godsend giving me positive reinforcement that I was on the right path. I've learned that if you live leaner today, and pay cash as you go, in the long run you'll actually live a better life than one with debt.
