Regret for the things we did can be tempered by time; it is regret for the things we did not do that is inconsolable.

The difference between patriotism and nationalism is that the patriot is proud of his country for what it does, and the nationalist is proud of his country no matter what it does; the first attitude creates a feeling of responsibility, but the second a feeling of blind arrogance that leads to war.

If the devil could be persuaded to write a bible, he would title it, "You Only Live Once."

Skepticism is not an end in itself; it is a tool for the discovery of truths.

People decline invitations when they are "indisposed" physically, and I wish they would do likewise when they feel indisposed emotionally. A person has no more right to attend a party with a head full of venom than with a throat full of virus.

Making out an invitation list for a party brings out the worst in everyone. It is then that our most ruthless estimates of the people we know come into play.

Never take the advice of someone who has not had your kind of trouble.
