I don't want to try to be less intimidating at work.
That's strange. Why do you want to intimidate people at work?
I am a man of few words and my intimidation is what I feel is required to achieve the goals.
This is bad behavior that will bite you in the butt sooner or later. Instead, you should act professionally at all times while at work.
But I prefer that everyone fear me. I want to be in control of everyone at my workplace.
Fear is not a good way to get people do to things for you, eventually they will get tired of it and it will backfire on you. You should act more professionally at work and you will see that it works better than fear.
