My cousin is getting married this year, and the family is very lively. During the dinner, when talking about buying a house, I couldn't help but think of my piano teacher.

She taught piano in her old house for twenty years, and finally chose to exchange the money she saved for a house to buy a Steinway piano. She believes that a house confines people, but music can take people to a farther place.

Her approach enlightened me: we always equate possession with security, but true security comes from the ability to choose. Her value is embodied in the keys of the piano, not locked in a property deed.

This reminds me of Buffett's wisdom: what matters is never what assets you own, but your ability to continuously create value. People who can swim don't ask where the shore is; those with real skills never worry about having no place to settle.

Perhaps maturity is being able to distinguish what others tell you you must own, and what you truly need and can master.
