Most journaling habits fade within weeks. The research points to two culprits, forgetting and boredom, and both can be designed around.

Three Good Things asks you to write down three things that went well each night. Here is the original 2005 study, its numbers, and its real limits.

A one-minute gratitude habit costs about 6 hours a year. We ran the numbers against federal time-use data and what the studies say about dose.

Stuck on what to write? We pulled the actual instructions and example entries from published gratitude studies and turned them into prompts.

Gratitude journals do nudge well-being up in controlled studies, but the effects are small. We turned the published effect sizes into plain odds.

A 2015 replication of Ebbinghaus's forgetting curve shows how fast new material fades, and a 1,354-person study shows when a review brings it back.

73 percent of U.S. adults call themselves lifelong learners. Here is what the Pew data says they want, and a low-effort way to learn one new thing a day.

Americans average 5.16 hours of leisure a day and 16 minutes of reading. Here is what 2 minutes of daily learning adds up to over a year.

In a classic experiment, students who quizzed themselves recalled 61 percent a week later. Students who reread four times recalled 40 percent.

Americans 65 to 74 have 6.9 hours of leisure a day, and 4.2 of it goes to TV. A daily fact by text is a small way to spend a little of it learning.

74 million US residents speak a language other than English at home, 61% of them Spanish. The 2024 Census numbers, and what they say about what to learn.

The State Department says Spanish takes 690 class hours. At 15 minutes a day that is 7.6 years. Here is the math, and what it means for a daily habit.

A meta-analysis of 35 studies found written corrections improved accuracy (g = 0.59), and most of the effect lasted. What that means in practice.

A review of 317 memory experiments found spaced study beat massed study in 259 of 271 comparisons at equal study time. What it means for learning a language.

Students who kept recalling 40 Swahili words remembered 80% a week later. Those who kept rereading them got 36%. Why producing words beats reviewing them.

Training days need more water than rest days, and the gap is where most people fall short. A goal that changes by day and a count kept by text makes it simple.

Most people do not fail to drink water because they dislike it. They forget, for hours. A plan that works with a bad memory: two texts a day and a count.

We mapped CDC county estimates of adults sleeping under seven hours: from 25% in Boulder to 51% in rural Alabama, tracking inactivity closely.

The median American adult falls asleep at 11pm and wakes at 6:30am on weekdays. We pulled the CDC's survey data to see how that shifts by age and on weekends.

We ran the numbers on the CDC's national sleep survey. Adults sleep 41 minutes longer on weekends, and those who need the catch-up most get the least.
