Success is a team sport which some leaders fail to realize. Some as a way of dealing with their complex or for the fear of their inadequacies being sported prefer to work alone or with a select few they find less smart than they are.
The job of a leaders does not lie in an individual who works alone or by themselves. A leader thrives better when they learn to work with others, by harnessing collective intelligence to solve defined problems. They get better and a more lasting result through others, in a team environment.
Business success is never a solo effort. An executive who cannot function in a team comprising of critical minds is suffering from incompetence complex. Always being fired-up by being told things they want to hear by team members is the beginning of downward slide to failure and contempt.
