How do you keep your momentum in trying to pay off credit cards?

I recently returned to work after having been a stay at home Mom of my youngest (twins) who are now 4. I vowed to use my pay solely for paying for child care and all these credit cards we've amed. I guess I should actually even be thankful to have found a job. I want to pay off these cards, but need suggestions on how to keep it foremost in my head and heart. I am almost tempted to post these billings where I have to look at them daily. I just paid off one this morning (a lower balance one) and bought some kitchen chairs we literally had to have, but no table, as our chairs were falling apart, with cash. Paying with cash is new to us, as we just loved the plastic too much. I also am vowing from this day forward to take my lunch, no McD's dollar menu for lunch anymore. How do I keep momentum in having the pep and excitement to pay these off? Any suggestion welcome : )
