Everybody is special, which means nobody is special. Each of us is unique. But that is no big deal; every snowflake, ice-crystal, cloud or wave upon the ocean is unique. So what is so special about each of us? Probably our opinion about ourself and the opinions we assume others have about us.
If we are able to look objectively at ourselves - and that's a big if - then we will note that we have different body sizes, shapes and colouring. But that's a taken as is. Our interpretation of what Nature gave us, and how we treated what Nature gave us also comes into it. For example, if we consumed more calories than we burnt over a long period of time we will be overweight.
Looking a our gifts, talents. Did we develop them or let them 'die on the vine?' We all have something or somethings we can do really well. If we take a pride in them and use them without being too vain about it, then we are special in this area. The concert pianist is special. Then so is the truck driver who can manourver a forty-two wheel monster in a small parking area. Our skills make us special...yet, deep down, all of us are not special. We are human beings.
