From the book The Secrets of Numbers

A basic premise of Numerology is that all things in nature evolve in cycles that are measurable and predictable. It follows that, as an integral pail of nature, the course of each human life is measurable and predictable.

In Numerology, your birthdate is the key to your personal series of cycles. From several simple calculations using the numbers of your month, day, and year of birth, you can construct a timetable which can give you personal direction. Your Numerological Timetable indicates the kind of environmental circumstances you will probably encounter, the things that are likely to happen to you, and the types of people you are likely to meet.

Do not be misled into thinking that your Numerological Timetable is fatalistic. To better understand its use compare life to one long improvised movie. Each of us is the director of our own movie. We impose upon it the stamp of our own individual character. Your Numerological timetable is an outline of the sets and the basic characters of the actors. You must work within the limitations of the sets and the limitations of the actors, but you may create with them what you will. By understanding the character of the setting and the actors, you can create the most perfect movie, or the most perfect life for yourself.

In other words, your individual response to what happens to you is as important as the circumstances that occur. You have the choice and the power to confront any situation, no matter how disagreeable it may seem at the time, and turn it to your advantage.
