" I am not bound to win, but I am bound to be true. I must stand with anybody that stands right, and stand with him while he is right, and part with him when he goes wrong." - Abraham Lincoln 

This quote gives you advice that you shouldn't win when something wrong comes along with that. Always be true no matter what is what Abraham Lincoln wants us to understand. Always stand right even though its just you and stand wrong when you know its wrong. Abraham Lincoln wants us to know this because he wants us to make better choices.
