A small summary, if can help you.

“Not all of us can do great things. But we can do small things with great love.”
Sometimes the smallest things that often go unnoticed make the biggest impact. Tell your co-worker good morning, kiss your wife, complement your child, hug a parent, or pay for the person that is behind you in the drive thru at McDonalds.
