Instead of spending an hour on Netflix, imagine learning from a brilliant MIT professor who shows you how to present your ideas clearly, powerfully, and with a clear purpose.
I get asked this question a lot: what's your favourite episode of The Diary Of A CEO ever?
The answer is fairly easy.. episode 101 with @MGawdat. It was our most shared episode ever, not because of fame or celebrity, but because what he said was so profound it changed the way I think about life..
Mo was the Chief Business Officer at Google X, the "moonshot factory" behind self-driving cars and some of the most futuristic technology on the planet. He co-founded over 20 businesses. By any external measure, he had achieved everything. But he was desperately unhappy..
So he did what any engineer would do - he tried to solve the problem. He spent years researching, collecting data, and eventually he discovered what he calls the happiness equation.
It's deceptively simple...
"You're happy in your life when your expectations of how life is supposed to be going are met. And you're unhappy when those expectations go unmet."
Therefore... so much of our happiness is about the gap between what happens and what you expected to happen."
I use this as a framework now to think about why I'm unhappy at certain moments in my life.
And it's always.. without any exception.. because I had an expectation of how something was going to happen and it's currently falling below that expectation.
This also explains why gratitude has always been seen as one of the great answers to happiness.
Because gratitude is the realisation that your expectations are being met in various areas of your life right now.
If you think about everything that's made you unhappy in the last week, I guarantee it's all about an expectation you had about something.
Someone cuts you off in traffic? You expected them not to. Your partner didn't do what you asked? You expected them to. Your dog pooped in the house? You expected it wouldn't.
So can we manage our expectations? of ourselves, of others, of our partners, of life itself?
Mo's son Ali died suddenly during a routine operation. It was the ultimate test of his equation. And somehow, through the worst thing a parent could ever endure, his framework helped him survive.
Have you listened to this one yet? ❤️
Dropped the phrase "product slop" today in a call — when teams can ship so much more at 100x the speed, the risk of bloated, feature-dense but unfocused experiences quickly becomes a concern. "More things faster" is rarely a recipe for excellence.
When it takes weeks to ship, you justify every feature.
When it takes hours, you ship everything. Why not? It feels like progress and momentum, right?
When the cost to build something was higher, and took more time, the need to justify the build and ensure it was oriented to mission and incrementally valuable (aka the *right thing* to build) helped mitigate this. With the cost and time effectively dropping to zero (I can code a complete product feature tonight after dinner) — everything changes about how we build high-quality products. Judgement and taste become the constraint.
Unsurprisingly, I believe design plays an even more critical role in this new world than ever.
@darrinhenein@hnshah You’re right! Ultimately it comes down to taste. Bringing the best of human experience into your product is the goal of the product creation team.
@KiwiThinker There are several research groups doing this, and of course there's this company in Ireland called Exergyn who recently raised a significant Series B to fund their project and product development. Interesting stuff!
