Even when the wind moves the arrow, you can still aim well. A gentle look at trying your best when the result is out of your hands.
The real source
“The archer's proper work is to do everything that lies within his own power to take aim well: to stand, to draw, to release with care. Hitting the mark, though preferred, is not the archer's; once the arrow is in the air, it is the world's. We do not say the archer failed when the wind moved his arrow. We say he aimed well.”
Cicero, in the voice of Cato · On Ends (De Finibus) 3.22

For grown-ups
This is not telling children that results do not matter. It is teaching them not to measure their worth only by outcomes. The target matters; the child is responsible for the aim.
A little practice: When something does not land well, ask: what was my aim, and what was wind?
The line your child keeps in Pocket: “Take care of your aim.”
