Forget the word “successful.” There is judgement associated with that.
I’m thinking of a concept analogous to a boat at sea. One without a sail or engine is pushed whichever way the ocean goes, and could, by luck, end up in a desirable location. Compare to ships with different engines where the best quality one will take the ship wherever the sailor desires. A ship with a strong engine may be turned off because the sailor decides to nap, or do whatever else they please, yet we never get to see the power of the ship, which is fine. Not a perfect metaphor but hopefully it works (and it’s the best I can come up with at 5am and can’t sleep).
I view Tesla as someone who did impressive work on his ship yet for some reason was prevented from achieving his goal of bringing that work to the people on the shore.
I do view many quirks as essential to the recipe, like obsession, and have benefitted from that in my own life. I’ve noticed it around me as well, in Silicon Valley, many talented technical people who could be achieving a better realization of their goal yet are made to believe they are better off giving away their freedom to build another food delivery app to make someone else rich. I view many talented academic types falling in similar patterns who fail to see some of the bigger picture.
However, as I type this I realize there are many ingredients to achieving your goals on earth, which of course must include luck (whether good or bad). But I do believe that luck isn’t everything, and in many cases it includes how you handle good or bad luck.
