1. 50 hours 🤝

That's how long it takes to turn a stranger into a casual friend. 90 for a real friend. 200+ for a close one. Jeffrey Hall measured it in 2018.
Nobody has 200 spare hours. That's why adults stop making friends.
Not shyness. Math.
🔧 Fix: stop chasing new people. Pick one acquaintance and repeat. Same gym, same café, same day. Hours stack only when you show up again.

2. 40% 🚇.

Economists Stutzer and Frey found that someone with a one-hour commute needs about 40% more pay to be as happy as someone who walks to work.
Almost nobody gets that raise.
People take the bigger house and the longer drive and call it a win. It isn't.
🔧 Fix: next time you choose a job or a home, price the commute in hours per year. 250 workdays, two hours a day, 500 hours. That's three months of full-time work, unpaid.

3. 120 minutes 🌳.

A 2019 study of nearly 20,000 people found well-being jumps once you spend about two hours a week in nature. Below that, almost nothing. It doesn't matter if it's one long walk or ten short ones.
Two hours. A week. Most people still don't hit it.
🔧 Fix: count it. Park, forest, river, beach. If the week ends under 120, you know why you feel flat.

4. One weekend 🏖️.

In 2021, researchers told one group to treat their normal weekend like a vacation. Same weekend, same plans. On Monday they were happier than everyone else.
The weekend didn't change. Attention did.
🔧 Fix: no chores list on Saturday morning. No checking work mail. Act like a tourist in your own city for two days.

Four numbers. None cost money. All cost attention.
