First major savings goal was when ex-husband and I knew that I would go to graduate school and we wanted to be able to let me go to an Ivy League school if I was accepted and pay for the first year's tuition in cash. We also wanted to pay off our cars. We did it in one year - was amazing to both of us how much we'd been wasting of our salaries - we started bringing our lunches to school, stopped cruising the mall on weekends, used the library a lot more, stopped eating for dinners, bought furniture and clothes either only on sale or second-hand, negotiated for prices to things - it all added up and quickly.
I actually ended up going to a school that paid me to go there, but that money saved gave us a cushion when a few years later we both were out of jobs. I still practice those frugal habits today towards my early retirement goal.
