Let us consider, first, the need for a tough mind, characterized by incisive thinking, realistic appraisal, and decisive judgment. The tough mind is sharp and penetrating, breaking through the crust of legends and myths and sifting the true from the false.

Martin Luther King Jr.

The tough mind is sharp and penetrating, breaking through the crust of legends and myths and sifting the true from the false.

The brain can be developed just as the muscles can be, if one will only take the pains to train the mind to think.

The mind is everything. What you think you become.

There is no illness of the body except for the mind.

We are what we think we are.

Frame your mind to mirth and merriment which bars a thousand harms and lengthens life.
