You can do anything you think you can. This knowledge is literally the gift of the gods, for through it you can solve every human problem. It should make of you an incurable optimist. It is the open door.
Robert CollierIt is your work to clear away the mass of encumbering material of thoughts, so that you may bring into plain view the precious thing at the center of the mass.
Robert CollierWe can do only what we think we can do. We can be only what we think we can be. We can have only what we think we can have. What we do, what we are, what we have, all depend upon what we think.
Robert CollierAs fast as each opportunity presents itself, use it! No matter how tiny an opportunity it may be, use it!
