I like to call it "Exposing yourself to luck." You can't win lottery if you never play. Play the lottery with the best odds and play it as much as you can.
I think it’s just trying to be exposed to as many opportunities as possible with the best tools you can have. You can’t determine whether or not you can catch a fish, but you can acquire the best fish-catching tools you can get, try to get to the fullest river, and stay out there as long as you can. I think the role of “luck” really hits when you realize how some people are born on the side of the river with a gigantic, well-made net.
