From a young age, Thomas Edison was willing to do the work. He grew up poor and got his first job at the age of twelve. He never had the chance to get a formal education.
Through books, experiments, and practical experience at various jobs, Edison gave himself a rigorous education that lasted about ten years, up until the time he became an inventor. What made this successful was his relentless desire to learn through whatever crossed his path, as well as his self-discipline. Mastery by Robert Greene
As he did the work, the opportunities came. And in time, he became one of the most prolific inventors of all time with over a thousand patents credited to his name.

When I think about all the things I really want in this world, I must remember that they are not so lofty as to be unattainable. Most of it requires only one thing to make it possible. I must do the work. It is not by luck that those hard-earned victories will fall into your lap. You gotta do the work!
Opportunity is missed by most people because it is dressed in overalls and looks like work. -Thomas Edison
