What worked, and what did you have to re-learn?
My parents taught me mostly everything I know about money, although when I started off on my own I had to relearn some basic concepts. Luckily, my parents were very good about making me pay off my credit cards in full each month so I don’t have any credit card debt.
One thing my parents taught me that I had to relearn was to balance a checkbook. To me, the idea is a little outdated with online banking. I now pay for EVERYTHING with my credit card, even if it’s a buck or two. I never write paper checks anymore and use my bank’s ability to send electronic checks. This way I can easily track all of my spending. Granted there will always be some cash purchases but through my method I’ve found I spend over $40 a month on my daily coffee.
