Your first work day began the moment you stepped out of your house. On the way to work, you would have never known when you would actually come into contact with your co-workers or boss. When you had finally made it to your new workplace, you must have taken a deep breath and walked in with a smile on your face. Perhaps your head was kept constantly and confidently up high and you were always remembering to make eye contact when communicating with others. Naturally politeness and friendliness to everyone you encountered, whether it was the receptionist or the mailroom clerk, your colleagues or your new boss, would have exhausted you enough for the whole week, on just that first one day.
