Saying no is self-respect

‘”No” and “Yes” are words quickly said, but they need a great amount of thought before you utter them.’ – Baltasar Gracian, 17th century Spanish priest. Someone — I wish I remember who — said something that’s followed me quietly for years: “Saying ‘yes’ to others should never come at

Inside a mind-bending seminar

“Classes will dull your mind, destroy the potential for authentic creativity.“ – John Nash (1928-2015), mathematician WHILE completing my dissertation on interest rates, I had the distinct pleasure of taking a seminar with Columbia University mathematician, Andrew Gelman, a former student of John Nash.

Gold FOMO in full swing

GOLD is all the rage now.  The rush for physical gold is leading to shortages.  It is also bringing back an old discussion – how much gold do central banks keep, why do they keep it and where do they keep it? Central banks are the biggest buyers of gold. 

Confidence bleeds too

“You didn’t hold my hand, but you had my back.“ – Elizabeth Melissa Heloise (Bella) messaged me after she and her classmates accidentally turned the school lab into a mini fireworks show during their science project last month. CALL it whatever you want – growing up, coming of age, a

‘Education is not the filling of a pail, but the lighting of a fire.’ – William Butler Yeats (1865-1939), recipient of the 1923 Nobel Prize in Literature. One complaint I hear from every parent who needs to send their kid to primary school: “Aiyo, some take so long to drop

The world is paying for Xi’s mistakes

But he is

Seen it all before

The question isn’t who’s going to let me; it’s who is going to stop me? —Ayn Rand (1905-1982), Russian-born American writer and philosopher The intense and hostile clash in the Oval Office among US President Donald Trump, Vice President JD Vance, and Ukraine’s Volodymyr Zelenskyy has astonished many observers. For

The geometry of insanity

I first heard about John Nash from Professor Andrew Gelman, his former student—who also taught my Bayesian Nash Equilibrium lecture.  On day one, he assigned A Beautiful Mind, Sylvia Nasar’s biography of Nash. It’s a hell of a book—459 pages of brilliance, madness and redemption.  Nash cracked game theory, spiralled
