If your boss asks you to move a box from point a to point b, it's probably not okay to say, "I don't feel like it right now."
If you work on the chain gang and it's time to dig a ditch, you don't get a reprieve if you roll your eyes and say, "that's not what they pay me for."
And if you're a dishwasher, you don't get a chance to say, "I guess I'm just not the kind of person who's good at putting his hands into really hot soapy water all day."
And yet when we ask you to look people in the eye, be creative, brainstorm, be generous, find a way to satisfy an angry customer, work with a bully, learn a new skill or bring joy to work, suddenly the excuses pile up. Is this a different sort of work? Is raising your hand in class too much to ask of you?
The jobs most of us would like to have are jobs like this. And yet we put up a fight when given the chance to do them well.
