"You are fettered," said Scrooge, trembling. "Tell me why?"
"I wear the chain I forged in life," replied the Ghost. "I made it link by link, and yard by yard; I girded it on of my own free will, and of my own free will I wore it."
-- Charles Dickens, "A Christmas Carol"
Habits are a chain we forge in life--a chain that can pull us down, or lift us up.
A nice marriage of the theme of habits and the holidays! I'm impressed I pulled that off.
