he will, and he may know by a rule that is pretty infallible whether it
is good or not, from his own experience in doing it. Did it give him
pleasure? Did he love it as it grew under his hand? Was he glad and
willing with it? Or did he force himself to it, and did it hang heavy
upon him?

There is nothing mystical in all this; it is a matter of plain, every-day
experience, and I think nearly every artist will say the same thing about
it, if he examines himself faithfully.

If the young contributor finds that he has no delight in the thing he has
attempted, he may very well give it up, for no one else will delight in
it. But he need not give it up at once; perhaps his mood is bad; let him
wait for a better, and try it again. He may not have learned how to do
it well, and therefore he cannot love it, but perhaps he can learn to do
it well.

The wonder and glory of art is that it is without formulas. Or, rather,
each new piece of work requires the invention of new formulas, which will
not serve again for another. You must apprentice yourself afresh at
every fresh undertaking, and our mastery is always a victory over certain
unexpected difficulties, and not a dominion of difficulties overcome
before.

I believe, in other words, that mastery is merely the strength that comes
of overcoming and is never a sovereign power that smooths the path of all
obstacles. The combinations in art are infinite, and almost never the
same; you must make your key and fit it to each, and the key that unlocks
one combination will not unlock another.
