The 13 secrets of Power Performance
Roger Dawson

Prenctice Hall Press

“Within each of us is a hidden store of energy. Energy we can release to compete in the marathon of life. Within each of us is a hidden store of courage. Courage to give us the strength to face any challenge. Within each of us is a hidden store of determination. Determination to keep us in the race when all seems lost.”

Neal Ascherson

Hill and Wang

“This death or near-death of a sea was not caused by the human race. It apparently annoys some fanatics that an ecological catastrophe can be achieved by ecology itself, without any need to call on expert human assistance. All the same, it was the natural action of natural forces which brought about this huge act of pollution: the decay of billions of tons of up-country mud and leaves and living ooze and dead micro-organisms, poured onto the sea floor since the last Ice Age by five great rivers of the Black Sea.”
