Lots of adults say they wish they hadn’t quit piano. You almost never hear someone wish they’d quit sooner.

Regret runs one direction with long slow skills. The cost of continuing is paid in small boring amounts you feel right now, and the cost of stopping is paid years later in a sentence that starts with wish. That imbalance is hard to see at fifteen, when the lesson feels like an hour you do not have.

Before you drop something that takes years, try shrinking it instead. Fewer lessons, shorter sessions, an easier piece you actually like. If it has become joyless, say so to whoever is paying for it and ask for a change rather than an end.
