A lot of judgments in this world are the result of disagreement. This person votes republican, or likes the wrong sports team, or is a vegetarian, or didn’t go to college, or any number of things, therefore I already know I’m right. If this sounds like you at all, then I encourage you to step back and look.
The entire world is full of different opinions, that’s what makes it such a great place. Embrace it and don’t limit yourself. Listen to other people’s opinions, respect them without judgment, and appreciate that we as humans are able to have such differing opinions and still thrive so much as a species.
Would you rather be right or be happy? I choose happy, how about you?
