To be alive is to experience pain, sometimes physically, other times psychically.
Remember this the next time someone lashes out at you with no provocation. It doesn’t excuse their behavior, but realizing it’s not about you can make it a lot easier to deal with.
Often people just want someone to listen and treat them with respect. As simple as this sounds, these kind of interactions are apparently in short supply.
Be the kind of person who exhibits these traits and see what happens. Other people will watch you and emulate your behavior.
You can change the world one human interaction at a time.
