We are all created different in terms of purpose in this World. Each of us meets a need and we are all part of a plan set by God. When we try to fit and be like others, not only do we lose ourselves, but also loose sight of our destiny.
Our aim in life should be to discover what we are meant to be as individuals and then succeed at that despite the limitations we would face. Eventually, we may not win every battle along the way, but would win the war itself.
