Failure can be a great teacher if you are willing to listen and learn its lessons. In Common Sense Is Not That Common, David Kottler offers a very frank and personal look into the ups and downs of business, offering entrepreneurs and business professionals insight into what it takes to overcome challenges and succeed. David shares 11 key principles he learned during his business career, including those gleaned during years of working alongside his father in the family's food distribution business. It's been said that a smart man learns from his mistakes while a wise man learns from the mistakes of others. In this vein, David offers readers a look at how to turn failure into opportunity. With charm, devotion, and a touch of wit, David credits his late father, whose voice echoes throughout the book, for teaching him the most important guiding principles for living one's life.
