Every time there is a boom cycle fools rush in. I don’t know why someone would expect that luck would be adequate to any large task. Luck is the default conditions to even get started.

And you have to keep doing it until one person who compounded so much effort and will that what looked like luck is simply habit and habit becomes process and process becomes results and results get sustained.
And yes decay sets in. And it gets harder. Every gain requires the energy that it requires. Leverage is often simply about being the one that makes it for the long haul. Maybe discretion is the better sort of valor but I’ve yet to meet a winner who was a coward.
