1. He was an adviser to Donald Trump

    Unsurprisingly, that didn’t work out, with Musk quitting the President’s advisory councils, which he’d joined – along with other tech executives – a month after the election. Musk announced he was quitting in June after Trump pulled the US out of the Paris climate accord.

  2. He’s a school dropout

    Musk enrolled at Stanford University to study physics in 1995, but dropped out after two days when he decided that the internet gave him more opportunities to impact humanity.

  3. He was a dreamer

    As a child, Musk’s mother, Maye, would often find him staring silently into the distance and feared he was hard of hearing, leading doctors to remove his adenoids. It turned out he was just daydreaming, as she told his biographer, Ashlee Vance: “He goes into his brain, and then you just see he is in another world … Now I just leave him be, because I know he is designing a new rocket or something.”

  4. He collects mansions

    Musk has spent US$70 million on buying no less than five mansions in Bel Air, Southern California, a billionaires’ playground. Because one mansion is never enough.

  5. He’s a Diet Coke fiend

    Staying awake long enough to work the 100-hour weeks Musk was regularly pumping out during the early days of setting up his companies is not easy, so he hit the caffeine hard, averaging almost three litres of Diet Coke a day.

    Plus some coffee. The results were predictably unhealthy, with Musk saying he was “so freaking jacked that I seriously started to feel like I was losing my peripheral vision”.
