Said another way, watching professional tennis and some other things one might see on screens are really not “models” for activities in which many participate, as the relevancy between the professional and the amateur act has “a lot of basis error.”

To wit, we have the internet. We have financial people who are often interviewed or often “tweet/blog/etc” for any variety of reasons, including the feeling that people around them are tired of listening to them so, wow, we have these zillions of fresh meat eyeballs out there. Whatever.

Stanley Druckenmiller is an investment legend. He is also a proponent of “I can change my mind and move billions in the opposite direction in 11 minutes, so if I say something smart at 11am, you would be an idiot to follow what I said at 11am.”

And he knows himself as best he can. You don’t. This pip just struck me as apropos of a lot of things. So, make your own mistakes is my takeaway.
