Stop Stacking. Start Testing.

“What supplements help ADHD?” is a shopping query. Here are the four questions that actually decide whether a supplement can do anything for you.

You Hit a Learning Plateau. Now What? Here’s How to Break It.

You are putting in the same hours, running the same drills, and you are exactly as good as you were a month ago. That is almost never a talent ceiling. It is practice that stopped containing new information, and adding hours to it buys more of the same nothing. Here is what eight studies show about why progress stalls, why your own sense of a good session is the worst guide to whether you are learning, and the four changes that actually restart it.

What Supplements Can and Cannot Do for Your Learning

I take a lot of supplements and none of them ever made me better at learning. What the good ones did was stop my brain from being the reason a study session fell apart. Here is what five trials actually found on theanine, bacopa, lion’s mane, creatine and rhodiola, who was studied in each one, and why almost every positive result came from a population with a deficit rather than a healthy learner looking for an edge.

Why a Long Break Doesn’t Help with Productivity After Deep Work

You take a break to reset. You come back, sit down, and the focus never shows up. Sophie Leroy’s research on attention residue found that part of your attention stays behind on whatever you left unfinished, and it gets worse when you dread the return. The fix isn’t a longer break. It’s a one-minute note written before you stand up.

The Group That Read It 14 Times Remembered Less

In a 2006 experiment, students who re-read a passage about 14 times recalled 40% of it a week later. Students who read it once and then tried three times to remember it recalled 61% — and the re-readers were the most confident they would do well. Re-reading isn’t useless; it’s optimized for the wrong test.

Your Brain Is Spiraling. Try This 5-Minute Reset Before You React.

A Stanford-led randomized trial found that five minutes of cyclic sighing a day improved positive mood and slowed resting breathing more than meditation did. But the study tested it as a daily practice, not the emergency reset most people treat it as — and that changes how you should use it.
