means Someone who does the job, and does it to the expected standard, regardless of what they actually feel about it in the moment.

from Traces back to Latin 'professus' — one who has openly declared or avowed something, from 'profiteri,' to declare publicly. It first described those who had taken vows into a religious order, then spread to anyone who had publicly committed to a vocation — law, medicine, the clergy. The 'profession' was originally the declaration itself; the composure came later, as the job requirement nobody wrote down.
