When do we stop practicing?

Lawyers, when they stop being lawyers, say they "stopped practicing law." If you have been a lawyer for 20+ years, you would be practicing law for a long time.

I'm a musician, and I don't say that I am "practicing music." Or should I?

At what point do we stop practice and become masters?

Or are we in a continuous practice with effortless mastery being nothing but an illusion?

Because if what we're in is a practice, that means we can get better at it.

Because maybe what we're actually mastering is the practice.

May we never stop.
