The harsh truth is that the most important driver in the growth of your assets is how much you save, and saving requires discipline. Without a regular savings program, it doesn't matter if you make 5 percent, 10 percent, or even 15 percent on your investment funds. The single most important thing you can do to achieve financial security is to begin a regular savings program and to start it as early as possible. The only reliable route to a comfortable retirement is to build up a nest egg slowly and steadily. Yet few people follow this basic rule, and the savings of the typical American family are woefully inadequate. It is critically important to start saving now. Every year you put off investing makes your ultimate retirement goals more difficult to achieve. Trust in time rather than in timing. As a sign in the window of a bank put it, little by little you can safely stock up a strong reserve here, but not until you start.
