No patience with others
As Entrepreneur.com points out, a manager needs to be able to listen and work with different personality types. If you quickly tire of interacting with people, you are bound to find managing a team difficult.
Inability to delegate work
A managerial role requires trust in the abilities of others. If you feel that you do everything best on your own and are unable to delegate work to others, this is guaranteed to become a problem.
Avoiding conflict
Conflicts are a natural part of the work environment. The ability to resolve them effectively and constructively is an essential skill for any manager. If you ignore conflicts or fail to resolve them in the long term, they can escalate over time and ultimately damage the team significantly.
Unable to take responsibility for your actions
A team leader must be prepared to accept responsibility for decisions and the results of the team. If you tend to find fault everywhere but in yourself, you are likely to be unsuccessful and uncomfortable in your management role.
Lack of leadership skills
If you struggle to inspire and motivate others, and gain their respect and trust, you will find your role as a manager extremely difficult. While charisma and different leadership styles can of course be learnt, you should not lack at least a little natural authority from the outset.
