I love this:

Whether I’m working on a kata or a breakable toy or even production software; I throw away most of the code I write. Why? Because my first attempt is a poor attempt. I use my first pass as a “spike”, a kind of hands-on learning opportunity.

and this:

Turning the knob to 11 is when you take a very specific concept; and over-apply it. Over-applying a technique or technology is the easiest way to find its shortcomings. Want to learn to TDD? TDD everything for a year. At the end you’ll have a solid understanding of when to and when not to TDD.
