Can a person be calm yet energetic?
They are not contradicting qualities. The opposite of calm is wild or disturbing. A person can be always very calm and energetic and all most all successful people are calm and energetic. Calmness is a quality of the mind that can stay undisturbed irrespective of what may come. Energetic is the physical as well as mental attitude to situations and work. Doing your work wisely planned, on a time bound schedule and working it up quickly and effectively show your energetic approach. Here, what actually happens, is controlling your energy and making use of it profitably on a very systematic way. You will never be this organized and effective (energetic) in executing your work unless you are calm inside.
