An Unprogrammed Life: Adventures of an Incurable Entrepreneur, by William H. Saito. John Wiley & Sons, 2012, 241 pp., $24.95 (paperback)

William H. Saito has enjoyed many successes in his short career as an information technology entrepreneur, but he is keen to stress the importance of failure.

"If you're not making mistakes, you're not trying hard enough," Saito stresses in his fascinating autobiography, "An Unprogrammed Life."

Yet Saito nearly learned the cost of mistakes to his peril, after a failed youthful experiment with nitroglycerin that fortunately exploded only some equipment rather than causing injury.
