how to make your self unique and valuable ?

well, isn't everyone unique already ? If you try too hard to be an image in your mind,then that's not really being 'you'. You don't make yourself valuable, you just believe that you are. Nobody is exactly like you and some people will see that, some won't. Some people will like you, some won't. Some people you attract, others you don't. There is nothing less unique than trying too hard to be unique.
