Haste vs. Hurry

“Though I am always in haste, I am never in a hurry,
because I never undertake more work than I can go through
with calmness of spirit.”

~John Wesley (as quoted in Ordering Your Private World)

Why was Wesley okay with “haste,” but avoided “hurry“? What’s the difference?

How can we accomplish our work with “calmness of spirit”?
