Sister Faustina, a Franciscan Sister of the Renewal, spoke this past March at a Source+Summit retreat. She pointed out how critical every action and decision we make really is:

"If you don't live what you believe, you begin to believe what you live."

Even in little things, like leaving a conversation that turns to criticism or only watching half of a movie in order to make a promised phone call, if we do not live what we believe (being kind when speaking of others or having integrity to make that phone call when our friends tell us to stay and watch the movie), what we hold dear will begin to matter less to us. Our actions will prove it.
