Many people have grit not all of them become successful.
Steve Jobs was lucky he met Wozniak.
Luck here seems to be the lazy way of explaining events.
Rather, Steve Jobs likely felt the need to pair with a very smart engineer in order to do what he wanted, and came upon Wozniak.
There was only one Wozniak in the world at that time, remember that very few people had that knowledge, time (being very young) and hands-on experience on electronics.
Since I am replying deep on this thread, I just want to say that Steve Jobs had also some rare skills but they were very lucky to meet in the world. I don't know of any other country, beyond UK (ARM/BBC/Acorn/Sinclair/Amstrad), where you can have this early access to computers and electronic components.
You are confusing what you would like to be the case (that you can predict success purely by human factors) with what is the case (that success is also probatilistic.
To claim that it's to encompassing makes no sense. If you want to truly understand instead of chanting some simplistic catchprases we entrepreneurs like to tell us self then it cant be encompassing enough.
Life is mostly probatilistic and we have much less control of our lifes than we would like to tell ourselves and each other.
Elon Musk, first generation immigrant, didn't come from money, is now a billionaire. An article was released this week interviewing Mr Musk where he plainly states he put his desk at the end of the assembly line in th Hawthorne Tesla factory. He then went on to mention how he has a sleeping bag and often sleeps there.
One of my favorites is to look at how many awful failures Abraham Lincoln went through. It would have broken most people, yet he soldiered on and ended up being one of the most important Presidents in US history: www.abrahamlincolnonline.org/lincoln/education/failures.htm
Virtually everyone on HN knows how much of an obscene work-a-holic Steve Jobs was. He was also a first generation Syrian immigrant. Luck? He was fired as CEO from Apple before founding Pixar and NeXt. He still refused to give up. Grit doesn't mean being a work-a-holic though, it simply is extreme perseverance.
This inability to fail but sheer willpower is called grit. You're underestimating the power of raw unadulterated willpower if you take things outside of your comfort zone and to the extreme. Those people did, and your great grand children will likely hear their names.
Yet another take on Mark Cuban, Richard Branson, and Larry Ellison. The common thread in every one of these stories is grit, the inability to accept failure at face value and continue on until you succeed.
