In the book of Proverbs (27:19), we find an amazing formula for peace. "As in water, face is to face, so too is the heart of one person to another."
When you look at your reflection in a pond or in a mirror, you will see the exact same expression that is on your face. If you frown and scowl, you will see a frown and scowl staring right back at you. And if you smile and wave, you will see a smile and a wave. This is a natural law of physics. To frown and expect to see a smile on the image of your face in a mirror isn't a wise expectation.
King Solomon teaches us that this natural law has a counterpoint in the laws of human nature. The inner feelings you experience towards someone will be reflected back to you from the heart of that person.
See the good in other people. See them as being souls who have high aspirations even if at present they are not yet using all of their potential. See people as they will be when they are at their best. Judge people favorably. See the positive intentions of what they say and do even when it would be preferable if they chose better ways to accomplish those positive intentions.
The way to influence people to feel better towards you is to radiate unconditional love and respect towards them. When someone likes and respects you first, it's easier to reciprocate those feelings. It is a step towards greatness to be the one to create unconditional love and respect when you need to sustain this in the face of challenges. Be willing to take this step.
