Even in the best MBA programs, there are some management strategies that you have to learn on the job. On the other hand, some of the industry’s best business leaders can also clue you in! Small Business Trends collected the 13 best management techniques that schools won’t teach you, and I’m happy to have contributed advice, tips and my own experience. Active listening is something I’ve learned in my years as a manager, founder and entrepreneur.

It’s something no book can teach you. It takes practice, and you simply have to get out there and do it. The good news? You can practice active listening in all parts of your life!
