Success or failure depends more upon attitude than upon capacity successful men act as though they have accomplished or are enjoying something. Soon it becomes a reality. Act, look, feel successful, conduct yourself accordingly, and you will be amazed at the positive results.

It is well for the world that in most of us, by the age of thirty, the character has set like plaster, and will never soften again.

Results should not be too voluntarily aimed at or too busily thought of. They are sure to float up of their own accord from a long enough daily work at a given matter.

Once you accept an idea, it's an idea whose time has come.

Our theories are wedged and controlled as nothing else is. Yet sometimes alternative theoretic formulas are equally compatible with all the truths we know, and then we choose between them for subjective reasons. We choose the kind of theory to which we are already partial: we follow 'elegenace' or 'economy'

We are mere bundles of habits.

Our lives are like islands in the sea, or like trees in the forest. The maple and the pine may whisper to each other with their leaves ... But the trees also commingle their roots in the darkness underground, and the islands also hang together through the ocean's bottom.
