It's always easier to apologize for something you've already done than to get approval for it in advance.

If you do something once, people will call it an accident. If you do it twice, they call it a coincidence. But do it a third time and you've just proven a natural law!

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

I had a running compiler and nobody would touch it. They told me computers could only do arithmetic.

It's easier to apologize than ask for permission.

Humans are allergic to change. They love to say, 'We've always done it this way.' I try to fight that. That's why I have a clock on my wall that runs counter-clockwise.

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