Competitiveness may be local/relative (against peers, a la climb the ladder) or global/absolute (against giants, a la advance humanity). In both cases, it is usually healthy at different stages of life if it acts as a nudge instead of an obsession. Obsessive competitiveness is too much too often a high risk / low reward game, but you only live once and then be it as you like: self-reflection and evaluation will however come, later.
