Being able to own up to what you need to do as a leader is what is needed. You have to be able to share all details with your staff. 

I love the learning tab of being a considerate leader, I have worked for many leaders who did not grasp that concept and due to missing that that leader always had turn over often. The best practice I can say that has made me  effective leader is understanding that we are all human. Being able to have that boundary of respect and being considerate of others and managing that is what can make any leader very effective. 

When you look at your groups performance  it is one of the best types of feedback as a leader. 

You cannot grow relationships and be successful if you cannot listen . Being able to understand and practice certain technics can create strong bonds and grow you as person. When you cannot listen you cannot grow. 

Learning what are the best practices for group meetings are very important.  I believe very much in the preparation before group meetings and having strong leadership as well. There are many opportunities for group meetings to go "off the rails" and there is nothing worse than leaving a group meeting and not feeling accomplished. 

I have learned that over many years communication is the key to success. What I have also learned is that how you communicate is also key as well. You cannot develop and grow in anything if there is no communication. Using Proper communication is very important as well an understanding when to use certain portals of communication

Being able to take a breather and understanding what you can and can't control is key to staying sane for myself. I suffer from high anxiety and being able to understand how to manage my anxiety,  which also creates stress for myself, has helped me grow as a person. Just remember it's about your perception of things as well. Sometimes being stressed means you are doing something right. 

I love the thought of listing your strengths and weaknesses , and being more detailed about them. It can help keep it clear and not so broad. When you have high expectations, with details and dates it can motivate you to accomplish help turn those weaknesses into strengths.
