Many in their career have an ambition to get someplace high , that too quickly. No issues with that. They want to be somebody big at any price, which does become an issue. The guys who talk better and present well usually are more heard and hence fall in the radar for any promotions- if (s)he is backed by their credibility, great, but if not, this becomes a situation for the company. The cost encountered by the organization though may be disenchanted employees, attrition of the good ones, and definitely a lack of loyalty to the organization. I always say ” Coaches do not play, they need not have been great players either, but they need to bring the best amongst their players in the team – they must though know how to play “. Careful selection of the deserving does make this better.
