I worked with a colleague who is in her 60's who seems has a lot of energy. She said she loves to work and would not want to take days off if she could. I asked her what makes her motivated to work everyday. She said jokingly if you see your bills that gets you kicked out of bed. She is hyperactive at work and she could work 12 hours all week without taking days off. I can get exhausted at the end of the day just like everybody else and working long hours is not my cup of tea. Is there something wrong with her? Is that an indication that she may be manic or ADD?
