Others may do the same job as you, live in the same area as you or have the same life experience as you, to a degree, but they are not you. You are a unique happening. You are also an essential part of this thing called life. The world needs your unique perspective and contribution to make the world a better place.
If you think you are ordinary or even less than some level of importance then you are underestimating yourself. You can thrive given the right environment and right self belief. Sometimes we need to find the right environment first. This could be a place of work or a group of friends. It is easier to believe in ourselves if others believe in us first.
