Who should rule by Eduardo Bellani
If you want to become a (better) leader, you should master the four essential characteristics for leaders: integrity, judgment, competence, and vision(Hogan and Kaiser 2005):
- Integrity. A leader must be trusted to be followed.
- Decisiveness. Making reasonable decisions in a timely manner.
- Competence. Both your followers and your stakeholders must know that you not only mean well but that you can deliver.
- Vision. Setting goals under the right strategy is vital for team and company success against its competition.
