Realize one’s strengths and accept limitations. Though one may be a good fighter/ boxer in lower division, yet one’s overall buildup may not reach the heavy weight division. Accept it and try some other things that can match your strong points, such as language or IT or culinary skills. One should be able to look into the mirror each day and smile at oneself, acknowledging all the good qualities one has. If one does not appreciate one’s own positive qualities, it will not be easy for the others to appreciate us.
