Poem about learning by example

I'd rather see a sermon than hear one any day;
I'd rather one would walk with me than merely show the way;
For the eye's a better pupil, and more willing than the ear.
Fine counsel is confusing, but example's always clear.

And the best of all the creatures are the ones who live their creeds,
For to see the good in action is what everybody needs.
I soon can learn to do it, if you let me see it done;
I can watch your hand in action, but your tongue too fast may run.
And the lectures you deliver may be very wise and true,
But I'd rather learn my lesson by observing what you do.
For I may misunderstand you, and the high advice you give,
But there's no misunderstanding how you act, and how you live.
