You must have been in a better position than us. We have tons of medical bills to pay off and considering we've only been sending them 10-20 apiece (before the snowball), paying them off isn't freeing up much cash. It's going to take a long time before our snowball starts to grow significantly. Right now we're throwing approx. $300 a month at our debt. Considering how much debt we have, $300 a month isn't going to pay it off quickly.
It's hard to decide what all to give up. I don't want to deny my kids the opportunity to play sports - and that is costly. I have completely stopped buying useless things. Eveything I buy, I have budgeted for. However, when you budget in Halloween, Thanksgiving, Christmas, etc. there isn't much left for the snowball.
