The difference between reading of examples and setting the example is a matter of doing.
It is not a matter of knowing. Knowing more, knowing more accurate information, knowing the right people, knowing how to get ahead, knowing all of the shortcuts and hacks.
It is not a matter of being. Being better, being more educated, being in the right circle, being on time, being perfect, being more capable.
It is not a matter of having. Having more resources, having the slack necessary to innovate, having the greatest talents, having all the degrees, having a flawless background.
All these things can help, and if you have them all the better.
But in the end what matters is putting up with the tediousness and repetitiveness of doing, and sticking to it even when something new knocks at your door, even when no one is holding you accountable, even when it hurts.
