In response to the Quora thread “How can I be as great as Bill Gates, Steve Jobs, Elon Musk, Richard Branson?” Elon Musk's ex-wife Justine offered this great response.
Extreme success results from an extreme personality and comes at the cost of many other things. Extreme success is different from what I suppose you could just consider 'success', so know that you don't have to be Richard or Elon to be affluent and accomplished and maintain a great lifestyle. Your odds of happiness are better that way. But if you're extreme, you must be what you are, which means that happiness is more or less beside the point. These people tend to be freaks and misfits who were forced to experience the world in an unusually challenging way. They developed strategies to survive, and as they grow older they find ways to apply these strategies to other things, and create for themselves a distinct and powerful advantage. They don't think the way other people think. They see things from angles that unlock new ideas and insights. Other people consider them to be somewhat insane.
If you're not obsessed, then stop what you're doing and find whatever does obsess you. It helps to have an ego, but you must be in service to something bigger if you are to inspire the people you need to help you (and make no mistake, you will need them). That 'something bigger' prevents you from going off into the ether when people flock round you and tell you how fabulous you are when you aren't and how great your stuff is when it isn't. Don't pursue something because you "want to be great". Pursue something because it fascinates you, because the pursuit itself engages and compels you. Extreme people combine brilliance and talent with an *insane* work ethic, so if the work itself doesn't drive you, you will burn out or fall by the wayside or your extreme competitors will crush you and make you cry.
The whole thing is great. However, if you're reading this, perhaps you already have no chance.
They are unlikely to be reading stuff like this. (This is *not* to slam or criticize people who do; I love to read this stuff myself.) They are more likely to go straight to a book: perhaps a biography of Alexander the Great or Catherine the Great* or someone else they consider Great. Surfing the 'Net is a deadly timesuck, and given what they know their time is worth -- even back in the day when technically it was not worth that -- they can't afford it.
