It is pretty save to assume that we are average people and not special at all. But everyone is average people and not special at all. This means if others can achieve something, we can. If others fail, we fail as well. Others mean not only other people in the current age, but also other people in the past and in the future.
At the same time, we as well as other people are also unique. Each one of us is an unique individual.
