We had 12.9 gigabytes of PowerPoint slides on our network. And I thought, What a huge waste of corporate productivity. So we banned it. And we’ve had three unbelievable record-breaking fiscal quarters since we banned PowerPoint. Now, I would argue that every company in the world, if it would just ban PowerPoint, would see their earnings skyrocket. Employees would stand around going, “What do I do? Guess I’ve got to go to work.
