I'm a sucker for a good commercial. They can be inspiring and funny, make you laugh, make you cry, motivate you.
Two of my favorites are those created by Liberty Mutual. The illustrate the power of the simple good deed of kindness and how it can inspire others to pay it forward. You can see them spreading change right before your very eyes! Watch these and be inspired to continue to do those little kindnesses for your fellow humans, your roommates of this house we call Earth. I say "continue", 'cause I KNOW you're already doing it!
