Would you like me to tell you a dirty, little secret?
No one cares how hard you work. Sure, some people will notice if you seem to be working hard. Your spouse or companion might note that you seem tired, stressed, not as much fun, or just aren’t around much, but they care about the consequences, not how hard you work. Your boss might note happily that his staff seems busy, things are humming along, but you can be sure that when it is review time she gets no credit for “keeps staff very busy.” Nor will the boss give you extra points for being busy. It is about results.
People outside your personal life, beyond your coworkers, might notice that you are hard to contact, perhaps because you are so busy. But trust me, customers do not care why they can’t get hold of you, and they will not see it as a positive.
