Elon is a lot like Bill Gates. Very rich to start with, at the right location at the right time, with the right connections and some luck.
Fortune favors the prepared mind. Musk dropped out of Stanford to found a start up which was initially funded by angel investors (not uncommon in that era) snd which later was sold to Compaq for $300M.

Musk went on to found his online banking idea X.com using $11M of his share of the Zip2 sale. That became PayPal which eBay bought shortly after for $1.5B. For your information, the rate of startup failure in Silicon Valley back then was about 90%. Most of the 10% that succeeded were moderately successful. Having two big successes in a row is not luck. Add SpaceX and his other ventures and it becomes obvious he has some actual acumen.
Stubborn and very self-aware.
As are most successful people. Those are positive attributes.
He only joined Tesla after a year. Later, he tried to rewrite history through the courts.

Yes, his ego wants credit for what he did to make Tesla what it became. It isn't clear that would have happened without him (with his stubborn can-do attitude).
Nor his solar panel business. That was started by his cousins, Peter and Lyndon Rive.
You realize that many businesses are started by a group of founders who each bring something to the table, be it ideas, skills, contacts, money, experience, or some combination. Have you ever started a business or worked for a startup?
He's very good at sniffing opportunities. The only company that he started (Zip2) no longer exists.
That's an important skill. Ideas are easy--Silicon Valley was full of ideas during the dotcom boom. Unfortunately a lot of self-described smart people have little idea how to differentiate between ideas that have utility (and business potential) and those that are just cool (and expensive) research projects. Many tech people have no business acumen or financial knowledge (I am weak in these areas) and need to partner with people with those skills. It is pretty rare to find someone with both tech and business savvy.
He's also not an American by birth. He's South-African born and has a Canadian passport too.
So? Half of Silicon Valley tech workers are foreign born. At least he embraces most of the core founding values of the USA, something that has become much less common among tech immigrants in my experience.
