Divide and rule, a sound motto. Unite and lead, a better one.
Johann Wolfgang von Goethe
Make it a rule of life never to regret and never to look back. Regret is an appalling waste of energy; you can't build on it; it's only good for wallowing in.
The golden rule is that there are no golden rules.
George Bernard Shaw
Rowe's Rule: the odds are five to six that the light at the end of the tunnel is the headlight of an oncoming train.
The trouble with referees is that they know the rules, but they do not know the game.
