It’s an obvious truth that practicing something makes you better at it.
As any musician will tell you, this isn’t actually true. Practice something makes you more consistent and automatic, not necessarily better. Practice makes permanent, not perfect. To get better, you need both practice *and* useful corrective feedback. In some cases it’s possible to provide yourself with that feedback, and in others it’s not (thus why even professional musicians still take lessons).
