How to not be intimidating to others
The intimidation might be created by something you don't consciously control, such as excessive height that makes you tower over others, or your leadership position, but it is usually the result of how you communicate.
If you want to cease intimidating those around you, you'll have to adopt new ways of communicating. When people feel intimidated they usually become resentful and lose respect for the intimidator. Examine your interactions and ask yourself if you have a subconscious desire to manipulate others.
Most of us do not deliberately try to intimidate others.
While it may be enjoyable to get people to do what you want, it's preferable to motivate and inspire co-workers and family members rather than intimidate them into action.
This could easily become intimidating for the people around them.
