I have a paper to write and these are a few questions I have to answer but I am at a loss

Identify three management traits that the leader possesses, and explain why they are necessary to a successful manager.

How you can develop each skill or trait in your own life? Training, education, experience, etc. - but be specific (if you create goals they should be SMART).

What are possible disadvantages to having these traits? originally I had chosen leadership, communications, and adaptability. I cannot seem to find any disadvantages to communication or adaptability. Am I not being specific enough on my traits?
