TDD teaches you how to write tests at all costs. Once you know how to test in every conceivable scenario than you can discard TDD and replace it with the wisdom of what tests are useful and understand the real ROI of writing this test or that test. If you haven't forced yourself to get good at writing tests at some point then you will fail to write a valuable test simply because the cost of writing the test seemed higher than the return even though it was only because of your lack of skill in that department.
