Recently read it. The first part of how Pixar came to be was really really interesting. From his days in research to Lucas Arts/Film to Jobs. The rest was also a good read. I also recommend it.
edit: and then a couple posts later I read, of course, things are never as they seem. Depressing.
What I got from the book is how much luck was involved (which Mr. Catmull acknowledges). If Lucas had not sold them. If Lucas had sold them to someone other than Steve Jobs. If Steve Jobs had not been willing to blow 70 million on them as a computer company. If Steve Jobs had not allowed them to pivot to animation after blowing 70 million on them as a computer company. If any one of those things had not happened Pixar would likely not exist and Mr. Catmull would likely just be another employee of some other company.
Great book. If the history lessons don't get you, the leadership/management insights will. It should be required reading for anyone with aspiration in tech / creative fields.
