At first, I only laughed at myself. Then I noticed that life itself is amusing. I've been in a generally good mood ever since.

Almost all of the finer things in life are free or nearly free. You don't have to pay for the sky at night or snow in the morning or a kiss on the nose when you're sick. Forgetting that may put you at the mercy of those who seek to profit by convincing you to want whatever it is they have to sell.

Be sure to expose yourself to criticism: A fine polish requires an abrasive.

How can we live in freedom and maintain that we are entitled to *anything* that we can't get without the labor of others? Remember, if we are entitled to the labor of others, that makes slaves of those others.

I think one of the problems [with raising intelligent children] is compulsory schooling...and that children are sitting there and they are taught and told what to believe. They are passive from the very beginning, and one must be very, very aggressive intellectually to have a high IQ [...] the child is taught. Right from the beginning, it's a passive process. He or she sits there, and they simply try to believe everything they're told.

Suppose you're on a game show, and you're given the choice of three doors. Behind one door is a car, the others, goats. You pick a door, say #1, and the host, who knows what's behind the doors, opens another door, say #3, which has a goat. He says to you: 'Do you want to pick door #2?' Is it to your advantage to switch your choice of doors?
