Taleb is controversial indeed but he does not deal much bullshit. Here's an excerpt from his commencement speech at the American University of Beirut in 2016.
I hesitate to give advice because every major single piece of advice I was given turned out to be wrong and I am glad I didn’t follow them. I was told to focus and I never did. I was told to never procrastinate and I waited 20 years for The Black Swan and it sold 3 million copies. I was told to avoid putting fictional characters in my books and I did put in Nero Tulip and Fat Tony because I got bored otherwise. I was told to not insult the New York Times and the Wall Street Journal; the more I insulted them the nicer they were to me and the more they solicited Op-Eds. I was told to avoid lifting weights for a back pain and became a weightlifter: never had a back problem since.
If I had to relive my life I would be even more stubborn and uncompromising than I have been.
For example: Let’s assume the sole information I have about a gentleman is that he is 40 years old, and I want to predict how long he will live. I can look at actuarial tables and find his age-adjusted life expectancy as used by insurance companies. The table will predict he has an extra 44 years to go; next year, when he turns 41, he will have a little more than 43 years to go. For a perishable human, every year that elapses reduces his life expectancy by a little less than a year. The opposite applies to non-perishables like technology and information. If a book has been in print for 40 years, I can expect it to be in print for at least another 40 years. But – and this is the main difference – if it survives another decade, then it will be expected to be in print another 50 years.
