"Every year, HBS Professor Clayton Christensen teaches students that well-tested academic theories can help them succeed not just in business, but in life. He expounds upon those lessons in his book, How Will You Measure Your Life? (...) "You'll see that without theory, we're at sea without a map or a sextant," Christensen writes. "If we can't see beyond what's close by, we're relying on chance -- on the currents of life -- to guide us.""You'll see that without theory, we're at sea without a map or a sextant," Christensen writes. Christensen also believes that certain common business principles are misguided and even dangerous. In the following excerpt, he explains why focusing on marginal costs and revenues can lead to personal, professional, and moral failure."
