Every one knows that insufficient rest and gorging are not good for anyone, either physically or mentally.

Be ready to revise any system, scrap any method, abandon any theory, if the success of the job requires it.

I regarded our progress merely as an invitation to do more - as an indication that we had reached a place where we might begin to perform a real service.

For thirty years I have leaned toward the theory of Reincarnation. It seems a most reasonable philosophy and explains many things. No, I have no desire to know what, or who I was once; or what, or who, I shall be in the ages to come. This belief in immortality makes present living the more attractive. It gives you all the time there is. You will always be able to finish what you start. There is no fever or strain in such an outlook. We are here in life for one purpose: to get experience. We are all getting it, and we shall all use it somewhere.

Money is worth what it will help you to produce or buy and no more.

Don't find the fault, find the remedy

He who believes he can and he who believes he cannot are both correct.
