Ed Catmull, President and CEO of Pixar (now part of Disney) on how working with Steve Jobs was difficult.

Pixar could not have survived without Steve, but more than once in those years, I wasn’t sure if we’d survive with him. Steve could be brilliant and inspirational, capable of diving deeply and intelligently into any problem we faced. But he could also be impossible: dismissive, condescending, threatening, even bullying. Perhaps of most concern, from a management standpoint, was the fact that he exhibited so little empathy. At that point in his life, he was simply unable to put himself in other people’s shoes, and his sense of humor was nonexistent.
