My father and I weren’t very close, but he did leave me with some good things to remember including…

You can justify anything you want to yourself.
You can only spend your money once.
Don’t pay interest if you don’t have to. (In other words, be patient and wait until you have the money.)
Don’t buy a house on the low ground or near creeks/rivers/streams. (I’m glad I paid attention to that given all of the flooding in Georgia lately.)
