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.

Same for me... I just have finished the book and found it very very inspiring until I saw the posts here.
