This certainly corresponds to me personally. I used to put off testing, thinking I'd have more time later, but then I'd add "just one more" feature before doing testing, over and over again. The list of tests I needed to write would grow until it seemed overwhelming, making me somewhat depressed thinking about all the testing I still needed to do. Since shifting to TDD, I get into the habit of writing tests before writing code, and the depressing test-related feelings are gone, which makes me a much happier programmer.
