That is where the being away from the keyboard part comes into action. You have to actually meet with people to be able to talk them into giving you opportunities.
I don't mean physically being in the right place at the right time. I mean that you happen to be interested in and start a company at the right point in history, where a confluence of technological and societal factors enable you to be that one-in-a-billion person like Jobs or the Zuck. Just running around talking to people isn't going to make you Jobs or the Zuck. It's necessary, but definitely not sufficient.
Of course, that's not to say that you can't be a moderately successful entrepreneur if you "hustle" enough. Just don't expect to have books written and movies made about you. I know plenty of people who have started ventures in important niches and have found moderate success. There's absolutely nothing to be ashamed of if you exit for $10 or 20 million after a couple of years of hard work. But, going in, you have to be aware of the fact that you're almost definitely not going to end up a multi-billionaire.
