We must first know that emotional intelligence and success do not always go hand in hand. People can achieve the desired results with reason and not develop good relationships with others. When you work with such people, you easily overlook the fact that their success is based on personal skills. E.g. the motivation to work with people who find it difficult to work with is usually very high. We need to know that their success is based on a fairly high level of self-management and probably a high level of reason. Difficult people with great achievements are in the minority; about 90% of the most successful people have a high level of emotional intelligence.
