“To be neurotic is to spend one’s life perpetually replacing one worry with the next.”
Humor in Psychotherapy (2007)

Context: As a senator, I worried every day about the size of the federal deficit. I did not spend a single minute worrying about the effect of gays on the institution of marriage. Today it seems to be the other way around.

A Conversation with Ward Cunningham (2003), To Plan or Not To Plan
Context: To worry about tomorrow is to detract from your work today. Time you spend thinking about tomorrow is time you're not spending thinking about what to do today. The place you leave in the code because you think you'll need it tomorrow, is actually a waste of time today — and a liability tomorrow. It does more harm than good.

“When you control a man's thinking you do not have to worry about his actions.”
Preface <!-- p. 21 -->
Source: The Mis-Education of the Negro (1933)
Context: When you control a man's thinking you do not have to worry about his actions. You do not have to tell him not to stand here or go yonder. He will find his "proper place" and will stay in it. You do not need to send him to the back door. He will go without being told. In fact, if there is no back door, he will cut one for his special benefit. His education makes it necessary.
The same educational process which inspires and stimulates the oppressor with the thought that he is everything and has accomplished everything worth while, depresses and crushes at the same time the spark of genius in the Negro by making him feel that his race does not amount to much and never will measure up to the standards of other peoples. The Negro thus educated is a hopeless liability of the race.
