That's something I've told DD. She got lucky to get the opportunity--no way to foresee she'd have this chance. BUT she has worked very hard the last few years to be a good catcher/ball player which put her into the position to be able to step up.
IMO do your best. You just never know what might happen.
One of my favorite historical figures was Louis Pasteur, who discovered chirality, came up with a treatment for rabies, and invented pasteurization for milk and beer. Here in Wisconsin, we know the importance of milk and beer.
Some of Pasteur's discoveries, such as chirality (left-handed and right-handed molecules), were the result of an enormous amount of good luck. Sometimes his good luck was absolutely mind-boggling.
Pasteur's response to critics who said he was merely lucky: "Chance favors the prepared mind".
Chance also favors the prepared ball player.
Best of luck to the little Dinosaur. May she make the best of her opportunities. Doing so will open the way to more "luck".
