I have to disagree with one point: that writing tests doesn't make you a better developer. Here's why:

Writing a test requires you to think about your code in different ways than just creating it. TDD requires you to plan your code. And the more code you write, theoretically, the better your skills will be.

Now, will it make you the best developer? Probably not. I doubt writing tests is the most productive use of time. But for the practice of software development, writing tests is critical.
