Six mistakes mankind keeps making century after century: Believing that personal gain is made by crushing others; Worrying about things that cannot be changed or corrected; Insisting that a thing is impossible because we cannot accomplish it; Refusing to set aside trivial preferences; Neglecting development and refinement of the mind; Attempting to compel others to believe and live as we do.
Any man may make a mistake; none but a fool will stick to it. Second thoughts are best as the proverb says.

Inequality also is thought to be just; and so it is, but not for all, only for the unequal. We make bad mistakes if we neglect this for whom when we are deciding what is just. The reason is that we are making judgements about ourselves, and people are generally bad judges where their own interests are involved.
It is a mistake to make propaganda many-sided, like scientific instruction, for instance... As soon as you sacrifice this slogan and try to be many-sided, the effect will piddle away, for the crowd can neither digest nor retain the material offered.
