Right    

"Always do right."

 I believe this means that you always have to be making the right choices and you will have success in life. For example doing right are following rules and laws, also treating people the way you want to be treated, being fair and not cheating, because cheating is wrong and not right. Making right choices makes you a good person and people trust you with big responsibilities and treat you good.
When people choose the wrong they get consequences also not that much people trust them.And that is not good for your life and your future.When you need someone that someone would let you down and not help you at all.
