As a student of Murphy's laws, I keep them close by and study them now and then, if for no other reason than to keep me from doing stupid things. Which, alas, has sometimes not worked very well. Perhaps internalizing some of them is the reason I haven't bought into the merger, at least so far. Here are several:
Logic is a systematic method of coming to the wrong conclusion with confidence.
If something can go wrong, it will.
If everything seems to be going well, you have obviously overlooked something.
Enough research will tend to support your theory.
Every solution breeds new problems.
If your advance is going well, you are walking into an ambush.
The only thing more accurate than incoming enemy fire is incoming friendly fire.
An expert is one who knows more and more about less and less until he knows absolutely everything about nothing.
