Testing is not the point. The point is about responsibility.

I don't like the feeling, but I've got to say that a little fear makes me a more focused, more responsible programmer.

Listening, Testing, Coding, Designing. That's all there is to software. Anyone who tells you different is selling something.

I mean, source code in files; how quaint, how seventies!

Sometimes the problem has to mature before the solution can mature.

If you're having trouble succeeding, fail.

The business changes. The technology changes. The team changes. The team members change. The problem isn't change, per se, because change is going to happen; the problem, rather, is the inability to cope with change when it comes.
