A girl called Hana had been learning the guitar for a year. Her teacher set her a new piece — harder than anything before, the kind that sounds like a mess for weeks before it suddenly clicks. For the first few days the wrong notes were so discouraging that she found reasons not to pick it up. "I'll do double tomorrow," she told herself. Tomorrow she said it again. The guitar sat in the corner, and the longer it sat, the more the piece felt like a wall she didn't want to walk up to. Now her lesson is in two days. She can either cram in a panic, turn up unprepared, or do something she's never done before — be honest with her teacher about why.
