Your Brain on Ocean Water
Originally shared in Tuesday Notes on April 7, 2026. There's a moment that has stayed with me from our stay in the Dominican Republic. Floating in the ocean. Not swimming, not doing anything, just floating, completely held by the water. And at some point I just... screamed. Out of pure joy. The kind that catches you off guard because you didn't know it was in there waiting to be released. Then there was the jumping. Wave after wave, laughing from the belly like a child, the k

Why You Still Can't Relax on Holidays
Originally shared in Tuesday Notes on March 31, 2026. There's a very specific moment that happens on holiday. You're finally there. The place you were looking forward to. The beach is beautiful. The weather is perfect. Everything looks exactly like it should. And yet, somehow... you're not fully relaxed. Your body is there. But your mind is still catching up. You check your phone. Think about something small. Feel slightly restless for no clear reason. And then comes the thou

You're Not Happier on Vacation (Here's Why)
Originally shared in Tuesday Notes on March 24, 2026. Lately I've been thinking about how different everything feels when you're somewhere new. Not necessarily better. Just... more alive. There's actually a reason for this. Your brain is constantly trying to be efficient. It turns familiar things into autopilot, your commute, your routines, even conversations. It's not that your life becomes less meaningful. It just becomes... less noticed. But when you're somewhere new, your

Happy International Happiness Day!
Originally shared in Tuesday Notes on March 17, 2026. This Thursday, March 20th, is International Day of Happiness. Which made me think about something interesting. Psychology doesn't actually treat happiness as one single thing. Researchers often talk about two different kinds of happiness. The first is hedonic happiness. This is the happiness most of us think about automatically. Pleasure. Comfort. Good food, good wine, a sunny afternoon, laughing with friends, bingeing Lov

Women's Secret Superpower (Sorry Men)
Originally shared in Tuesday Notes on March 10, 2026. This weekend was International Women's Day, and it got me thinking about something fascinating in psychology. Research consistently shows that, on average, women are better at recognizing emotional expressions and subtle social cues. Psychologists have found that women tend to pick up micro-expressions, tone shifts, and mood changes faster than men. In simple terms: many women walk through the world with a slightly more ad

When Control Feels Like Safety
Originally shared in Tuesday Notes on March 3, 2026. Lately, the world feels loud. Unpredictable. Hard to make sense of. When the external world feels unstable, something subtle happens internally. We tighten. Not always visibly. But mentally. Emotionally. Behaviorally. We try to at least control something. The Psychological Layer There's a cognitive bias called the illusion of control. It describes our tendency to overestimate how much influence we have over events, especial

Why Deciding Is the Hardest Part
Originally shared in Tuesday Notes on February 24, 2026. One decisive second can change the next ten years of your life. Not because everything suddenly becomes easy. But because you stop standing in between. This isn't about effort. It's about taking a decision. There's a quiet but powerful difference between making a choice, and postponing a choice. Indecision feels neutral. Responsible, even. But staying undecided keeps you suspended between two versions of your life. The

Love, but Make It Neurological
Originally shared in Tuesday Notes on February 17, 2026. Before we talk about Valentine's Day, here's something I love: we're wired for connection, but not just the romantic kind. The same neurochemical systems that support romantic bonding, particularly oxytocin and dopamine, also activate in close friendships. Your brain doesn't reserve attachment for candlelit dinners and grand gestures. It responds to safety, warmth, shared laughter, emotional attunement. A long voice not

On Language, and Belonging
Originally shared in Tuesday Notes on February 10, 2026. This week's conversations around Bad Bunny performing in Spanish at the Super Bowl landed a little closer to home for me than usual. I grew up in a family shaped by many places; born in Panama, to a Swiss father and a mother from Trinidad and Venezuela, raised between Mexico and Switzerland. I learned early that language is a strange shortcut people use to decide where you belong. Speak it well, and you're expected to f
