We should respect all people.

As the eagle was killed by the arrow winged with his own feather, so the hand of the world is wounded by its own skill.

We can do anything we want to if we stick to it long enough.

I demand that the world be good, and lo, it obeys. I proclaim the world good, and facts range themselves to prove my proclamation overwhelmingly true. To what good I open the doors of my being, and jealously shut them against what is bad. Such is the force of this beautiful and willful conviction, it carries itself in the face of all opposition. I am never discouraged by absence of good. I never can be argued into hopelessness. Doubt and mistrust are the mere panic of timid imagination, which the steadfast heart will conquer, and the large mind transcend.

I do not want the peace which passeth understanding, I want the understanding which bringeth peace.

A child must feel the flush of victory and the heart-sinking of disappointment before he takes with a will to the tasks distasteful to him and resolves to dance his way through a dull routine of textbooks.

Your success and happiness lies in you. Resolve to keep happy, and your joy and you shall form an invincible host against difficulties.
