We are all wearing an invisible sign that says, “Look at me. I’m important.”
I know of many people who are in such need of validation they are walking up to everyone to tell them how important they are.
Guess what? No one really cares. When you talk about yourself you leave the other person feeling inferior. If you want them to validate you and feel good about themselves talk about them. Be less interesting and more interested. You will walk away and they will think to themselves, “That person makes me feel good about myself.”
