Psychology and Leadership
Nearly all good leadership courses around the world aims at creating self-awareness more than going through leadership theories and techniques. having the ability to understand the self enables the person to adapt to many situations which is necessary as a leader.
understanding others behaviours and the expectation in different situations is also important to support the leader self-awareness. for example, understanding the reasons which make followers resist is crucial to be able to use self-strengths and knowledge to handle it.
Having a clear and agreed-on vision is important but, in my opinion is not enough because it does not, as is the case for other leadership personal traits, create sustainability. having a vision, charisma, self-awareness, enthusiasm, and communication skills can make a leader but it does not guarantee that this leader can lead in different situations which is the case in real life under the continuously changing environment.
Psychology in my opinion, although it is frightening word for many, is important to deal with multi-cultural people, change, and to make more robust decisions.
