Isn't that what happens in life when we focus on competing with co-workers, neighbors and friends,trying to prove that we are more successful or more important? We spend our time and energy chasing after them and we miss out on our own paths to our future.
The problem of unhealthy competition is that it's a never ending cycle, and there will always be somebody ahead of you,someone with a better job,more money and more education,etc.
Therefore,just take what life has given you,your height,weight and personality.Stay focused and live a peaceful life.Although there's competitions in life,just work hard to run your own race and wish others well.
