I have tried TDD but it feels more natural for me to commence most
*new* projects or *hard* problems with a prototyping phase where I
hack code without any tests just to get it to work.  Afterwards, I
usually throw away a lot of that code and rewrite/restructure using a
TDD approach.  For small changes, bug fixes, or easy problems I always
use TDD.  The prototyping phase is risky but it's faster, easier, and
less wasteful (for example, you don't have irrelevant tests laying
