We recently created these postcards as a friendly reminder of the many things we can do today to set ourselves up for financial independence. The 3 Guidelines of Personal Finance is Spend Less, Earn More and Invest the Rest. These are what I also call the 3 Wealth Building Strategies. Do all 3 and you are sure to have a sizeable nest egg to help you fulfill your dreams, but I am going to change the order a bit and actually make it Invest First, Spend Less, Earn More.
