I am overzealous (work too hard) and become nervous when my co-workers are not pulling their weight (doing their job). However, I am aware of this problem, and before I say anything to anyone, I ask myself why the colleague is having difficulties.
: I work well under pressure. When there is a deadline (a time by which the work must be finished), I can focus on the task at hand (current project) and structure my work schedule well. I remember one week when I had to get 6 new customer reports out by Friday at 5. I finished all the reports ahead of time without having to work overtime.
