You still need luck to discover opportunities with the correct growth slope in the market gradient landscape, funding landscape, etc. Some of this is intelligence, but it's also "right place, right time" and "who you know".

But you also need the skill and hard work to execute, grit when facing headwinds, and vision to see the gradient landscape as it ascends and unfolds into the stratosphere. You have to be adaptable. Future thinking, but realistically grounded in implementable plans with a pragmatism for building things the market will want, avoiding the traps your biases may set up for you.

Jobs had all of this.
