Second this, Becoming Steve Jobs is the superior book. It helped a lot that the authors had interacted with Jobs over decades and also had an understanding of business and technology that Isaacson was missing.

There’s also an old documentary about the founding of NeXT that does such a great job of showing what it was like to be in the room with him as a member of a small team, and this was before he fully “became” Steve Jobs. People underestimate how much meaning can be found in being pushed hard by someone with a clear and inspiring vision.
