different?

differentiation. what's so different about me and you? unique physical features, height, weight, unique characteristics, caring, giving, honest, grumpy, cheerful. How bout clothes and accesories. People want to be differentiated from others, different handphones, unique ringtones, different fashion, drive different cars, live in different renovated houses. Differentiation.
Something that i learned today from one of the Tigers in the company i work in. How we should differentiate ourselves from our competitors out there.
But i guess it applies in life too sometimes. On how we sell ourselves, how different are we from the other people. What makes us unique?
