I don’t believe people are one dimension. They don’t consist of one way of doing things, or enjoy doing only one thing. They have different aspects about them. Many of these compose who they are.
Be careful on comparing someone’s single dimension to yours. This won’t make them greater than you, you still have different dimensions they don’t. You just aren’t looking for it. You are looking across the fence at the green grass, wanting what they have.
One single thing about you, doesn’t make you any different or special. It is the many things that compose you. Maybe you have forgotten? Then draw a line on a piece of paper. Write about significant events (good or bad) that have happened to you. Then on the other side, write what you learned from it. Write how it has formed who you are today. Focus more on who you are, have you have been changed and less on others. You do you.
