The remedy for weakness is not brooding over weakness, but thinking of strength.

The young people of today think of nothing but themselves. They have no reverence for parents or old age. They are impatient of all restraint. They talk as if they alone knew everything and what passes for wisdom with us is foolishness with them. As for girls, they are forward, immodest and unwomanly in speech, behaviour and dress.

I am neither bitter nor cynical but I do wish there was less immaturity in political thinking.

Even people who aren't geniuses can outthink the rest of mankind if they develop certain thinking habits.

The man who doesn't make up his mind to cultivate the habit of thinking misses the greatest pleasure in life.

High thinking is inconsistent with a complicated material life based on high speed and imposed on us by mammon worship.
