"A garden requires patient labor and attention.
Plants do not grow merely to satisfy ambitions or to fulfill good intentions.
They thrive because someone expended effort on them."
-Liberty Hyde Bailey
Here is a passage regarding intent vs. impact from "Above the Line" by Urban Meyer:
We have a saying that is fundamental to what we do:
I see better than I hear.
Or as Andrew Luck told me, "Your actions are so loud I can't hear what you're saying."
Sometimes we express it another way: Don't give me theory. Give me testimony.
We are not measured by our intentions, but by our actions.
