Thanks for the link to the video on "successful people". The message agrees with my own sentiment.Uri is a successful person, don't trust his advice.
However one should not confuse "successful people" with experts. Experts (as I would define them) are people with objectively quantifiable skills.
For example the message in the video does not apply to Uri. The difference is that one can be lucky (for a while at least) in predicting the stock market (or dice throws for that matter) but one cannot win chess games by pure luck.
