Six mistakes mankind keeps making century after century: 1. Believing that personal gain is made by crushing others; 2. Worrying about things that cannot be changed or corrected; 3. Insisting that a thing is impossible because we cannot accomplish it; 4. Refusing to set aside trivial preferences; 5. Neglecting development and refinement of the mind; 6. Attempting to compel others to believe and live as we do.
Though silence is not necessarily an admission, it is not a denial, either.
To find fault is easy; to do better may be difficult.
When you wish to instruct, be brief; that men’s [children’s] minds take in quickly what you say, learn its lesson, and retain it faithfully. Every word that is unnecessary only pours over the side of a brimming mind.
