But risks must be taken because the greatest hazard in life is to risk nothing. The person who risks nothing, does nothing, has nothing, is nothing. He may avoid suffering and sorrow, but he cannot learn, feel, change, grow or live. Chained by his servitude he is a slave who has forfeited all freedom. Only a person who risks is free. The pessimist complains about the wind; the optimist expects it to change; and the realist adjusts the sails - William Arthur Ward
