Perhaps pedantic, but "prepared mind" includes your meaning. Prepared may mean being equipped with a skill that meets the moments, but flexibility, acceptance and optimism are also skills of a prepared mind.

It's why the quote has survived since 1854.

> "dans les champs de l'observation, le hasard ne favorise que les esprits préparés" ("In the field of observation, chance favors only the prepared mind")

Not recognizing and pursuing opportunities is one of my greatest regrets in life. Going to work like hell to teach my kids different.

But however you want to spin it, there’s still the underlying luck, that you survived until that moment, that you were able to reach that place and that you were free to venture there are all inputs you didn’t have much or any control over. There’s no shame in it. I’ve achieved a good deal in a half century of life and much of it was via hard work and guile, but I do tend to think of myself as lucky because, even as a middle-class kid back when the US had that, where my starting blocks were placed on the track was far enough ahead of the bulk of the pack that these things became achievable.

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.

You won't always be right but you can be there often enough to matter. goals need to be reasoneble - the luck needed to be a billionair is unlikely, but if you settle for millionair that luck is likely if you invest your money in the right place.
