non verbal communication is just as important as verbal. 

be honest and sincere when speaking with people.

some people deal with stress in different ways, finding what helps you as an individual is key to maintain a good mental and physical health

bad bosses will say do as i say not as i do, a good leader will lead by example.

practice and studying what you are giving a prestation on will go a long way. it will also help with not having to look at your notes the entire time and engage the audience. 

good leader ship should already have this information in some way, weather they went to school or used what they have learned working for a bad manager and striving not to be that way when they have the opportunity to be a manager. almost everything this discussion talked about I apply in my interaction with employees or students. I may change the way I explain or interact with individuals based on how they learn or understand so I can have all of my employees and students maximize there potential.
