Vigorous writing is concise. A sentence should contain no unnecessary words, a paragraph no unnecessary sentences, for the same reason that a drawing should have no unnecessary lines and a machine no unnecessary parts. This requires not that the writer make all sentences short or avoid all detail and treat subjects only in outline, but that every word tell. -- William Strunk, Jr. (The Elements of Style)

Lisp is a programmable programming language. -- John Foderaro

What I didn't understand was that the value of some new acquisition wasn't the difference between its retail price and what I paid for it. It was the value I derived from it. Stuff is an extremely illiquid asset. Unless you have some plan for selling that valuable thing you got so cheaply, what difference does it make what it's "worth?" The only way you're ever going to extract any value from it is to use it. And if you don't have any immediate use for it, you probably never will. -- Paul Graham

We now come to the decisive step of mathematical abstraction: we forget about what the symbols stand for. ...[The mathematician] need not be idle; there are many operations which he may carry out with these symbols, without ever having to look at the things they stand for. -- Hermann Weyl, The Mathematical Way of Thinking

A hacker on a roll may be able to produce–in a period of a few months–something that a small development group (say, 7-8 people) would have a hard time getting together over a year. IBM used to report that certain programmers might be as much as 100 times as productive as other workers, or more. -- Peter Seebach

The best thing about a boolean is even if you are wrong, you are only off by a bit. -- Anonymous

It is better to fail in originality than to succeed in imitation. ~Herman Melville

People who succeed have momentum. The more they succeed, the more they want to succeed, and the more they find a way to succeed. Similarly, when someone is failing, the tendency is to get on a downward spiral that can even become a self-fulfilling prophecy. ~Tony Robbins

When I stand before God at the end of my life, I would hope that I would not have a single bit of talent left and could say, I used everything you gave me. –Erma Bombeck

The number one reason people fail in life is because they listen to their friends, family, and neighbors. ~Napoleon Hill
