The Power of Habit: Why We Do What We Do in Life and Business

Thu, 06 Apr 2023 00:00:00 +0000

Most of what you do all day, you don’t really decide. Charles Duhigg’s starting point is that roughly 40% of daily behavior runs on habit—automatic loops your brain builds to conserve effort. Researchers watching mice learn a maze saw brain activity fall as the route grew familiar; the animals had bundled a string of choices into a single automatic routine. Every habit, in humans too, follows the same three-part loop: a cue fires, a routine plays out, and a reward lands. Your alarm goes off (cue), you brush your teeth and brew coffee (routine), and the taste and jolt of caffeine (reward) close the circuit.

Emotional Intelligence: Why It Can Matter More Than IQ

Tue, 02 May 2023 00:00:00 +0000

We’ve been measuring the wrong kind of smart. Daniel Goleman’s argument is that the ability to notice your own feelings, name them, and steer them—while reading them accurately in other people—predicts how your life turns out at least as well as IQ does, and often better. A brilliant mind that floods with rage in every meeting or misreads every room will underperform a merely average one that stays composed. The hopeful half of the claim is that these skills, unlike raw intelligence, can be learned. Their near-absence from how we school and raise children is a cost that compounds over a lifetime.

The Let Them Theory

Two short phrases handle almost everything that drains you. Let Them releases your grip on what other people do. Let Me returns you to the only thing you actually control: what you do next. Mel Robbins found the idea while spinning out over her son’s prom, until her daughter told her to let the kids enjoy it their way. The stress vanished, and Robbins realized how much of her life she’d wasted forcing other people to match her expectations.

Master Your Emotions

Thu, 21 Sep 2023 00:00:00 +0000

Your emotions are chemical events moving through you, not the core of who you are. The anger, the anxiety, the low mood — each is a temporary state, more like weather crossing the sky than a permanent feature of your character. Thibaut Meurisse’s argument is that the sooner you see this separation, the more power you gain: you can step back, watch a feeling from a distance, and ask where it actually came from instead of being swept along by it.

Stop Letting Everything Affect You

Mon, 16 Feb 2026 00:00:00 +0000

The version of you that spirals over a single text, absorbs everyone else’s stress, and replays conversations for hours isn’t your real personality. It’s a pattern you’ve practiced so long it feels like identity. “The reactive mind isn’t who you are — it’s simply what you’ve practiced becoming.” That reframe is the whole premise of Daniel Chidiac’s book: hyper-reactivity is a learned habit, and anything learned can be unlearned.

Meditations

Wed, 22 Jul 2026 00:00:00 +0000

The most powerful man in the Roman world wrote this book for an audience of one: himself. It was never a book at all, but a private notebook kept at night on military campaign, where a Stoic emperor argued himself back into shape day after day. Some entries carry the place he wrote them, among the Quadi on the river Granua, at Carnuntum near the front. He is not teaching anyone. He is reminding himself of things he already believes and keeps forgetting under pressure, and the same handful of ideas circle back again and again: attend only to what is yours to control, do the work your role demands, and accept the order of nature you are a small part of.

Dopamine Nation

Wed, 22 Jul 2026 00:00:00 +0000

Your brain processes pleasure and pain in the same place, and it treats them like opposite ends of a balance. Feel pleasure, and dopamine floods the reward pathway, tipping the scale one way. But the balance hates staying tipped. It wants to sit level, so every swing toward pleasure triggers an automatic correction that pulls it back and, thanks to momentum, pushes it an equal distance into pain. Lembke pictures the correction as little gremlins hopping onto the pain side to cancel out the weight of pleasure. That after-reaction is why the second chocolate satisfies less than the first, and why the moment you crave one more is really the balance already dropping toward pain.
