Doing something that nobody on this planet could do will definitely matter. Why? Because there is nobody on this planet who could do what you are doing! Is it possible? I don’t know. But, there is no second Pablo Picasso, Steve Jobs, or Einstein but there could be your own version of them in their field.
So doing something just because of peer pressure or because of what others think or tell is definitely not a long-term game. You will definitely not enjoy what you are doing if you are doing it for others’ sake. It is always in the process and the end result may be the byproduct of what you do. You shouldn’t be attached to the result but for the experiences that you will have while you are in the process. Because the experiences that you have is all that matters as an individual in the end.
