Ego - narcissism - a desire to prove oneself because of feeling less than others while young - these are the dark and necessary motivators to feeling invincible and confident and that you can make your ideas reality. How arrogant must an entrepreneur be to believe that he can defeat and conquer multibillion industries?
Here's the secret though. There is no secret- there is only your fear of being laughed at and ridiculed and failing. People like Steve Jobs aren't confident because they try to be confident - confidence is a side effect of being stubborn and desperate. You are desperate to succeed because of the dark motivators I described above. You are stubborn because you desire success desperately, and will keep knocking your head against the wall until you achieve it. If you push your stubborn-ness and desperation to the extremes, eventually one day people will look at you speak, and think you were always confident and always powerfully-centered and in control. But they are just seeing the symptoms of a lifetime of failure and desperation and stubbornness that has finally begun to turn around.
What I am saying is - to be confident - be honest with yourself. If you want to be great, expose yourself, look ugly and feel insecure, but be stubborn in pursuing your honest desire to be great and do great things. Confidence will be gained by trying to do exceptional and weird things long enough until you realize you can achieve them.
You can see this in school culture: is the goal of school to get the stamp at the end, and you might get some knowledge in the process; or is it to get knowledge and you might get a stamp at the end.
You can see it in interviews: do you hire someone with ten years experience, or do you hire someone who can solve your whiteboard problems.
This culture of results mattering more than experience may come from the US history of being very spread out with a lot of people moving around. If some out of town person comes in looking for work and says they've been doing something for 10 years, it may or may not be true -- you ask them to show you how they can do whatever it is, and decide based on that; the truth of the background doesn't really matter.
This doesn't hold true completely. It's harder to get a programming job without a degree, but it's not impossible. It is impossible (or darn near) to get a job as a medical surgeon without an appropriate degree and supervised training, though.
Steve’s confidence can come at a cost too though. Steve was part of imposing work anti-poaching agreements so employees couldn’t easily switch jobs to certain tech companies. There’s also plenty of untold stories of Steve yelling at employees and making them cry. While I overall like Apple and would love to work there, it’s worth asking...
What else is behind the video? Are there people who’ve been hurt by Steve? Do you want to be that personality?
As far as handling your own confidence, it comes with time. I’d recommend learning to take some impromptu debate, a dance class, etc. to be around people more. Particularly outside circles of friends that belittle you.
Very few people will ever put in the kind of effort and time that Steve Jobs put into his work, and so they shouldn't ever expect anything like his level of expertise or confidence.
"While Mr. Jobs's stated positions on management techniques are all quite noble and worthy, in practice he is a dreadful manager ... He is a prime example of a manager who takes the credit for his optimistic schedules and then blames the workers when deadlines are not met," he wrote, adding that Steve "misses appointments ... does not give credit ... has favorites ... and doesn't keep promises."
I think Jobs was incredibly lucky that he was always surrounded by smart, humble people, such as Woz. Raskin was less tolerant. You say confidence; some say arrogance. Some admired him for that; others just didn't care; it seems.
He was lucky enough to rope in a genius - Woz - to make a computer he could sell brilliant - thanks to his narcisism, maybe - and make 100 million out of it. From then on he almost destroyed two companies - Pixar and Next - until he learnt how to run one properly at Apple 2.0
don't confuse the tech world in the USA today with the one at jobs time.
