Luck is a major factor in all types of success, and the failure to recognize this simple fact is a major factor in all later collapses.
Some people, at some point, start thinking that success is owed and inevitable.
They are perhaps very talented people, or people who put a lot of work and long hours into shaping something, or even incredibly creative people who have managed to change the rules in their industry, or again natural and charismatic leaders that suck others into their visions.
But should all this be a determining factor, there would be millions of billionaires and thousands of unicors and decacorns. And the best thing would be that once gotten there, there they would stay forever. They would own the recipe, after all.
Success is all of the things above, and yet it is mainly a series of unprecedented and unrepeatable circumstances that lined up to provide somebody or a group of people with an opportunity. If you are there, you most likely do not know how you got there, and you better not get too comfortable.
Appreciate the luck you have had, make it worth it (not only for yourself, ESPECIALLY not for yourself), and build resilience for when the moment will come for you to step out of the spotlight.
