+Nothing is as easy as it looks

+ Everything takes longer than you think

+ Anything that can go wrong will go wrong

+ If there is a possibility of several things going wrong, the

one that will cause the most damage will be the one to go wrong

+ If there is a worse time for something to go wrong, it will happen then 

+  If anything simply cannot go wrong, it will anyway 

+  If you perceive that there are four possible ways in which a procedure can go wrong, and circumvent these, then a fifth way, unprepared for, will promptly develop

+ Left to themselves, things tend to go from bad to worse

+ If everything seems to be going well, you have obviously overlooked something 

+  Nature always sides with the hidden flaw 

+ Mother nature is moody 

+  It is impossible to make anything foolproof because fools are so ingenious

+ Whenever you set out to do something, something else must be done first

+  Every solution breeds new problems

+ Trust everybody ... then cut the cards

+ Two wrongs are only the beginning

+ If at first you don't succeed, destroy all evidence that you tried

+ To succeed in politics, it is often necessary to rise above your principles

+ Exceptions prove the rule ... and wreck the budget

+ Success always occurs in private, and failure in full view.

+Nothing ever goes as planned.
