The most damaging phrase in the language is: 'It's always been done that way.'

If it isn't bolted down, bring it home.

You manage things and lead people.

To me programming is more than an important practical art. It is also a gigantic undertaking in the foundations of knowledge.

The only phrase I've ever disliked is, 'Why, we've always done it that way.' I always tell young people, 'Go ahead and do it. You can always apologize later.'

From then on, when anything went wrong with a computer, we said it had bugs in it.

If it's a good idea, go ahead and do it. It is much easier to apologise than it is to get permission.
