Nature always sides with the hidden flaw. Nothing looks as good close-up as it does from far away. In any given set of circumstances, the correct course of action is dictated by subsequent events. The only imperfect thing in nature is the human race. Good times end too quickly.
Bad times go on forever.
Anything is edible if it is chopped finely enough. Nothing ever goes away. A fool and your money are soon partners. Things get worse under pressure. If a series of events can go wrong, it will do so in the worst possible way.
