How does one change and improve the world? It is not necessary to invent outrageous things like cars, air conditioning, smart phones, computers, shoes, Google, or the Internet to effectively improve the world. Most people will never invent such magnificent things but that does not mean we are impotent to improve the world in our own little way. Many times all that is required to bring about positive change is to tell a joke, get somebody to laugh, give a hug, lend a compassionate ear to another person’s problems, spend quality time with another person, raise your kids to be gentle, compassionate, kind, and loving human beings. It costs $0.00 to be a decent person.
