In physics, Escape Velocity means the speed at which an object can break free from a planet's gravitational field. In the Think & Grow Balls! philosophy, however, it means the energy and momentum required to break free from your own mental, habitual, and gravitational pull so you can leave your old ways of thinking far behind... and become the person you are meant to be.
The Think & Grow Balls! philosophy was heavily influenced by:
Napoleon Hill Maxwell Maltz Carl Jung Brian Tracy Jack Canfield W. Clement Stone Melvin Powers Rhonda Byrne Anthony Robbins Joe Vitale Henry Ford Ralph Waldo Emerson Thomas Edison Theodore Roosevelt William Jennings Bryan Plutarch Henry Wadsworth Longfellow Harvey Mackay Og Mandino Plato Thomas Troward Nathaniel Branden Dale Carnegie Socrates Abraham Lincoln Robert Francis Kennedy Winston Churchill Epicurus Tom Hobson Norman Vincent Peale Helen Keller Henry David Thoreau William Shakespeare Slade Schuster Kurt Vonnegut Immanuel Kant Ralph Baergen Aristotle Friedrich Nietzsche Robert Neslund Jeff Sudmeier Eben Pagan aka David DeAngelo Neil Strauss Ross Jeffries
And, a huge credit goes to Wikipedia.org for providing the facts behind the theories I present and the many people I field-researched with to get the true meaning behind them.
