"You Big Dummy"

Why is it that I like to make things hard on myself?  I was doing some refactoring a class method ["Introduce Parameter Object"] and decided that I would just change the signature, rename the method, blah blah blah in one shot, why not, I was already there.  I can just hear Fred Sanford saying "You Big Dummy", go slow, one thing at a time, follow the steps. 

Actually it wasn't Fred, it was Brian, and he promptly went over to my bookshelf, grabbed my Refactoring book and hit me in the head with it.
