Getting excited for the new SoulPancake short this week? Browse through photos from the team's "Pop Your Problems" video shoot!

Be sure to watch "Pop Your Problems" on Sunday morning at 8 a.m. or noon ET/PT on OWN.

Intention: Sometimes the thought of "making change" can be overwhelming: Do I have time? I don't want to do it alone. Why don't I start next year? But here's the thing: Now is the time to change your mind and your perception. As you'll see in I Am, historian Howard Zinn says, "Change happens from millions of tiny acts."

Assignment: Perform one random act of kindness. Tell us what you did and inspire someone else to follow your lead.

Examples: Get creative: Buy a few newspapers and hand them out to your fellow subway riders. Leave a cheerful plant anonymously on a colleague's desk. Surprise your children with notes in their lunch boxes. Buy an extra cup of coffee and give it to the police officer outside.

Watch I Am on "Super Soul Sunday" January 1 at 8 a.m. and noon ET/PT.
