We have seen and heard other people describe themselves and these kind of descriptions sort of sink into our heads. The moment some one asks us to describe ourselves, we start off by using such hackneyed phrases.
I think it is much better to completely steer clear of hackneyed phrases. It makes us look like just another face in the crowd. Tell me, unless you have an identical twin, have you ever seen any one who looks exactly like you?
Then why on earth should your description of yourself sound like a banal organ that has been played again and again. Try to sound as original as you can. Make yourself sound interesting.
Try to use as many similes and comparisons as possible. If you are blonde, well dont just say that you are blonde. You could descriptions like, “My hair is the color of freshly harvested hay.”
“My hair color would make a raven blush.” If you have red hair, you could try something like, “My hair is like the setting sun.”
Another point that I would like to add is you do not have to belittle yourself. Every coin has two sides and it all depends on the way you look at it.
For example, if you have dark skin, there is absolutely no reason to feel bad about it. It all depends on how you put it across. You could try expressions like, “If you like chocolate then you are going to love the color of my skin.” Or “My body looks like polished wood.”
Remember, beauty lies in the eyes of the beholder, and it is left to you to convince the beholder. Most people are willing to believe what you tell them, provided you tell them convincingly enough.
