? You might want to travel or start a family. No matter how much you may want to have something, you will not acquire it if you cannot pay for it.Togather the funds, you need to plan carefully—and have self-discipline along the way. If you are saving or investing to meet a goal that will make you happy and financially secure, the sacrifices you make will be worth it.A savings or investment plan starts with a specific, measurable goal. For example, you may want to save $15,000 to make a down payment on a house five years after graduating from school.
