Don't compete with me: firstly, I have more experience, and secondly, I have chosen the weapons.

Progress is possible only if we train ourselves to think about programs without thinking of them as pieces of executable code.

The effective exploitation of his powers of abstraction must be regarded as one of the most vital activities of a competent programmer.

The use of anthropomorphic terminology forces you linguistically to adopt an operational view. And it makes it practically impossible to argue about programs independently of their being executed.

Aim for brevity while avoiding jargon.

Beware of "the real world". A speaker's apeal to it is always an invitation not to challenge his tacit assumptions.

Please don't fall into the trap of believing that I am terribly dogmatical about the go to statement. I have the uncomfortable feeling that others are making a religion out of it, as if the conceptual problems of programming could be solved by a single trick, by a simple form of coding discipline!
