I am a big fan of the Pay It Forward theory. Sometimes, it may feel like it doesn't work, and people may walk all over you, but I guarantee that if you do something for a starnger or anyone in need for no other reason than out of the goodness of your heart...great things can happen!
I try to do little things every day, but the oddest Act of Kindness I ever did was drive a friend and her aunts mother-in-law and dog to Manhattan for doggie chemo! Yes-I live in New York, but Manhattan is an 8 hour drive!
