No need for conjecture — Steve Jobs said as much multiple times (e.g. "Getting fired from Apple was the best thing that could have ever happened to me.") One of the unintended consequences for Jobs was working with Ed Catmull at Pixar in the early 90s, who by all accounts was an exceptional manager and leader, and helped Jobs develop on this dimension.

It seems I really have to get my hands on good Jobs biographie it seems.

Becoming Steve Jobs by Brent Schlender and Rick Tetzeli was a thoroughly enjoyable read for me, and captured the growth trajectory from the 1980s to the 2000s quite well.

Creativity Inc, which was written by Catmull, is an equally good read if you’re interested in the subject.

Yeah. It's a bit of a narrative rather than a fact, but from what I can tell he really did some big soul searching and learned a lot of useful, practical advice. IIRC there is some article describing him looking at a warehouse full of unsellable inventory and realizing that not storing computers, but building them near realtime based on demand, was a better way to not lose money.

That sounds more like Dell than Jobs.
