Disarming.... Are you stressed out or in a hurry and.....?

If you are trying to get across as being over-worked to impress your bosses, then it's okay. But, when you are meeting someone for the first time and desperately trying to convince that person, looking stressed out or hurried or impatience or contemptuous or negative or critical is not adding any value. Being desperate also do not count in your favor. It's better to be relaxed and disarming.
