The more badly written a program is, the less changes I wish to make for fear that it will have unknown and unexpected effects. Of course, that means that I only want to refactor code that is already well laid-out. ;-)

A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
