Our wisdom and deliberation for the most part follow the lead of chance.

The opinion of 10,000 men is of no value if none of them know anything about the subject.

Great wisdom is generous, petty wisdom is contentious. Great speech is impassioned, small speech in cantankerous.

First, have a definite, clear practical ideal; a goal, an objective. Second, have the necessary means to achieve your ends; wisdom, money, materials, and methods. Third, adjust all your means to that end.

Calmness of mind is one of the beautiful jewels of wisdom.
