It depends on how much you believe other people’s stated public persona.
If you believe it, then it helps model other areas of life in a way that undoubtably supports the outcome.
For example, not part of Mr Buffets persona (and I believe it!) is staying up until 2am getting wasted and having 5 baby mommas.
And so anyone trying to have even a shadow of Mr. buffets success should probably also avoid doing so, and perhaps do some of what Mr. buffet does instead. Like reading the financial papers.
Yes of course there's only one way to have a succefull life and one should just follow what others before them have already done, in order to be successful, who needs to think for themselves and make choices, just read the financial papers make a lot of money and then when you are dead and forgotten by the world at least you will have all your money to comfort you in the afterlife
Notably, Mr. Buffet didn't do that (per-se). But he certainly copied a bunch of habits which apparently worked for him. Or not. Who knows.
You can't get much beyond the median if you copy other people, unless you're really lucky. But if you handicap yourself constantly too, good luck even hitting the median.
