Sometimes in life we yearn to be like the one who we love, especially a kid who emulates his father in the early stages of life. Hence for every kid his father is the first hero in his life. But on the other hand a truly loving father would like to see his kid earn a unique name and position in this world.
Being unique doesn't mean you sway away from society, a garden has unique breed of flowers but still it is the unique collections of all such flowers makes a garden unique. You may be wondering what will you achieve after all those efforts of training your self to be unique? Its just about adding a unique flavor to the creation, hope I am clear about the significance of being unique.
To practice uniqueness you need to train your mind to see the uniqueness surrounding you in small aspects. But to be frank this world is trained to make an individual hate the uniqueness of the other individual for the reasons well known to the trainer. So if you want to train yourself to see the unique side of the world it is at your own risk.
But once you have trained your self to see the unique side of the world, you will be free from the herd mentality, a prerequisite to see how uniquely you can contribute to the world.
