The Golden Rule. I will let you remember or find out what The Golden Rule is, but will point out that Jesus said (in Matthew 7:12) that all the teachings of "the Law and the Prophets" can be summarized into this one concept. It is what Jesus was all about. We count years starting from the birth of this guy. I think he got it right. Thanks for your great question!
In every life a little rain must fall. Instead of complaining about it, learn to dance in it. Dance like no one's watching and sing like you can't be heard. Live free and love hard. Most importantly, let everything you do be to the glory of God.
Margret Thatcher Watch your thoughts, they become words. Watch your words, they become actions. Watch your actions they become habits. Watch your habits, they become character. Watch your character, it becomes your destiny. So you become your thoughts.
