Great people talk about ideas. Average people talk about things. Small people talk about other people.
"Character" is how you treat those who can do nothing for you.
"A man doesn't treat a woman like a lady because she is a lady. He treats her like a lady because he is a gentleman."
"We rarely, if ever, have a clue about what may be going on in someone's personal life. So...just be nice. It's that simple."
Many people don't know this, but it's entirely possible to read something you don't agree with on the internet...and simply move on with your life.
"True humility is not thinking less of yourself. It is thinking of yourself less." - C. S. Lewis
