There’s a difference between being able to do something,
and being able to do it with the regularity and professionalism required
to make a job out of it.
In childhood and youth, we’re taught to look to our interests and talents
when choosing a trade.
Yet far more important is the kind of lifestyle a job imposes on you:
A capable, even masterful practitioner may be better off,
and their talents better used by society,
when they make teaching their job instead.
