📝 The story behind the little key

A scientist of the brain

Mogi is a neuroscientist based in Japan who studies the brain and has written widely for general readers about happiness, meaning, and the mind.

Writing on ikigai

His well-known writing introduces many readers to ikigai, the Japanese idea of having a reason to get up in the morning, found in the everyday things that bring us joy.

Start with the small spark

A central point in his work is that we don't need a giant life-purpose to live meaningfully — that following the small things that genuinely light us up is where a good life often begins.

Pip the puppy stops hunting for a big purpose and follows the little spark that wags his tail — and it leads somewhere no one could have planned. That's the heart of ikigai, the idea Ken Mogi writes about: meaning grows from small joys.
