Greatest Phrase Of Wiki Ninety Nine

Nominations:

• PeterMerel's "I admit that my paranoia is wearing a bit thin" nominated by RichardDrake
• RonJeffries' "I've never been able to make a complicated system work. I've always had to make it simple first" nominated by GlennVanderburg. (This is a paraphrase from memory because I can't remember what page it's on. And since Wiki now only supports keyword searching, and the phrase contains no words that don't occur dozens of times on Wiki, I can't find it. Any help will be appreciated.)
• KentBeck's "ListeningTestingCodingRefactoring. That's all there is to software. Anyone who tells you different is selling something."
• ExtremeNormalForm
