Nassim Nicholas Taleb gave a Commencement Address to the American University in Beirut in 2016. Taleb has written "a philosophical and practical essay on uncertainty (Antifragile , The Black Swan, Fooled by Randomness, and The Bed of Procrustes), a (so far) 4-volume "investigation of opacity, luck, uncertainty, probability, human error, risk,and decision making when we don’t understand the world, expressed in the form of a personal essay with autobiographical sections, stories, parables, and philosophical, historical, and scientific discussions in nonoverlapping volumes that can be accessed in any order." More on Taleb.

His Commencement Address has some interesting life thoughts and as someone seemingly fond of aphorisms he ends on this:

The following are no-nos:

Muscles without strength,

friendship without trust,

opinion without risk,

change without aesthetics,

age without values,

food without nourishment,

power without fairness,

facts without rigor,

degrees without erudition,

militarism without fortitude,

progress without civilization,

complication without depth,

fluency without content,

and, most of all, religion without tolerance.

My highlights from his speech below. The full text is here.

For I have a single definition of success: you look in the mirror every evening, and wonder if you disappoint the person you were at 18, right before the age when people start getting corrupted by life. Let him or her be the only judge; not your reputation, not your wealth, not your standing in the community, not the decorations on your lapel. If you do not feel ashamed, you are successful. All other definitions of success are modern constructions; fragile modern constructions.

(I am happy to report, I'm pretty sure my 18 year old self would not be disappointed with me)
...

...the courage to do something unpopular. Take risks for the benefit of others; it doesn’t have to be humanity...The more micro, the less abstract, the better.

Success requires absence of fragility. I’ve seen billionaires terrified of journalists, wealthy people who felt crushed because their brother in law got very rich, academics with Nobel who were scared of comments on the web...

...But self-respect is robust –that’s the approach of the Stoic school, which incidentally was a Phoenician movement. (If someone wonders who are the Stoics I’d say Buddhists with an attitude problem, imagine someone both very Lebanese and Buddhist). I’ve seen robust people in my village Amioun who were proud of being local citizens involved in their tribe; they go to bed proud and wake up happy....


...Now a bit of my own history. Don’t tell anyone, but all the stuff you think comes from deep philosophical reflection is dressed up: it all comes from an ineradicable gambling instinct –just imagine a compulsive gambler playing high priest. People don’t like to believe it: my education came from trading and risk taking with some help from school....

...I skipped school most days and, starting at age 14, started reading voraciously. Later I discovered an inability to concentrate on subjects others imposed on me. I separated school for credentials and reading for one’s edification...Greed and fear are teachers. I was like people with addictions who have a below average intelligence but were capable of the most ingenious tricks to procure their drugs. When there was risk on the line, suddenly a second brain in me manifested itself and these theorems became interesting. When there is fire, you will run faster than in any competition. Then I became dumb again when there was no real action....
...I discovered along the way that the economists and social scientists were almost always applying the wrong math to the problems, what became later the theme of The Black Swan. Their statistical tools were not just wrong, they were outrageously wrong –they still are. Their methods underestimated “tail events”, those rare but consequential jumps. They were too arrogant to accept it. This discovery allowed me to achieve financial independence in my twenties, after the crash of 1987.
So I felt I had something to say in the way we used probability, and how we think about, and manage uncertainty. Probability is the logic of science and philosophy; it touches on many subjects: theology, philosophy, psychology, science, and the more mundane risk engineering...

...The second break came to me when the crisis of 2008 happened and felt vindicated and made another bundle putting my neck on the line. But fame came with the crisis and I discovered that I hated fame, famous people, caviar, champagne, complicated food, expensive wine and, mostly wine commentators. I like mezze with local Arak baladi, including squid in its ink (sabbidej), no less no more, and wealthy people tend to have their preferences dictated by a system meant to milk them. My own preferences became obvious to me when after a dinner in a Michelin 3 stars with stuffy and boring rich people, I stopped by Nick’s pizza for a $6.95 dish and I haven’t had a Michelin meal since, or anything with complex names. I am particularly allergic to people who like themselves to be surrounded by famous people, the IAND (International Association of Name Droppers). So, after about a year in the limelight I went back to the seclusion of my library (in Amioun or near NY), and started a new career as a researcher doing technical work. When I read my bio I always feel it is that of another person: it describes what I did not what I am doing and would like to do...

I am just describing my life. 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.

One should never do anything without skin in the game. If you give advice, you need to be exposed to losses from it. It is an extension to the silver rule. So I will tell you what tricks I employ.

• Do not read the newspapers, or follow the news in any way or form. To be convinced, try reading last years’ newspaper. It doesn’t mean ignore the news; it means that you go from the events to the news, not the other way around.
• If something is nonsense, you say it and say it loud. You will be harmed a little but will be antifragile — in the long run people who need to trust you will trust you.

When I was still an obscure author, I walked out of a studio Bloomberg Radio during an interview because the interviewer was saying nonsense. Three years later Bloomberg Magazine did a cover story on me. Every economist on the planet hates me (except of course those of AUB).

Treat the doorman with a bit more respect than the big boss.

If something is boring, avoid it –save taxes and visits to the mother in law. Why? Because your biology is the best nonsense detector; use it to navigate your life.

The No-Nos
There are a lot of such rules in my books, so for now let me finish with a few maxims. The following are no-nos:

Muscles without strength,
friendship without trust,
opinion without risk,
change without aesthetics,
age without values,
food without nourishment,
power without fairness,
facts without rigor,
degrees without erudition,
militarism without fortitude,
progress without civilization,
complication without depth,
fluency without content,
and, most of all, religion without tolerance.
