"Godlike genius.. Godlike nothing! Sticking to it is the genius! I've failed my way to success." -- Thomas Edison "Let me tell you the secret that has led me to my goal. My strength lives solely in my tenacity." -- Louis Pasteur "Men give me credit for genius; but all the genius I have lies in this: When I have a subject on hand I study it profoundly." -- Alexander Hamilton
Saying I worked hard is a more comforting story than saying I was lucky. I think people are likely to put more value on hard work than its due.
I have a friend who's smart, and is a really good listener. We have really good philosophical conversations, and he kicks my ass at board games. I've been wanting him to get into programming, because right now he's working as an assistant manager at a sandwich shop chain. He absolutely has the talent to understand programming, but he has never put an ounce of effort into it. He really likes the idea of making 50k/yr (which would essentially be a doubling of his salary) so he could be less depressed about finances.
I offer him help... I tell him how I self-trained into programming, without a C.S. degree. And he just has a total lack of effort, and I think that he just tells himself that he can't do it.
When we establish the narrative that the only barrier is hard work, then we ought to be able to motivate people because they'll recognize that most things are within their reach with enough determination.
