Learning & Mind Hobbies — The Hobby Closet

Researching your family history — part detective work, part archive diving, with genuinely surprising discoveries.

Acquiring a new language — a long-horizon hobby with unusually rich free resources.

Training attention deliberately — free, portable, and supported by a substantial research base.

A trainable skill with outsized career and social payoff — and a very supportive practice ecosystem.

The original hobby — cheap, portable, and the best-documented way to spend leisure time well.
