“Man’s mind may be likened to a garden, which may be intelligently cultivated or allowed to run wild.”

A person is limited only by the thoughts that he chooses.

Work joyfully and peacefully, knowing that the right thoughts and right efforts inevitably bring about the right results.

They who have no central purpose in their life fall easy prey to petty worries, fears, troubles, and self-pityings.

The dreamers are the saviors of the world.

The more tranquil a man becomes, the greater is his success, his influence, his power for good.

Men do not attract that which they want, but that which they are.

As a man thinketh in his heart, so shall he be.

He who has conquered doubt and fear has conquered failure.

Self-seeking is self-destruction.

If you would protect your body, guard your mind. If you would renew your body, beautify your mind. Thoughts of malice, envy, disappointment, despondency, rob the body of its health and grace.

What you are, so is your world.

For you will always gravitate toward that which you, secretly, most love.

The man who does not shrink from self-crucifixion can never fail to accomplish the object upon which his heart is set.

Circumstance does not make the man; it reveals him to himself.

A man’s worldly success will be in the measure that he sacrifices his confused animal thoughts.

The sole and supreme use of suffering is to purify, to burn out all that is useless and impure.

A great many people think that polysyllables are a sign of intelligence and refinement so they think they will impress others with their command of obscure words.

Each child should be more intelligent than his parents.

Nothing develops intelligence like travel.

Intelligence is characterized by a natural incomprehension of life.

Computers aren’t intelligent, they only think they are.

It is the very essence of intelligence to coordinate means with a view to a remote end, and to undertake what it does not feel absolutely sure of carrying out.

Intelligence increases mere physical ability one half. The use of the head abridges the labor of the hands.

In short, intelligence, considered in what seems to be its original feature, is the faculty of manufacturing artificial objects, especially tools to make tools, and of indefinitely urging the manufacture.
