Its difficult to pinpoint, as different people show different signs. But one truth cannot be denied: working on someone's orders is not as demeaning as many seem to think of it. Yes it is difficult to digest at times because of ego, especially when it is your colleague or friend calling the shots on you. However, if we can only practice hard on ignoring the ego and letting it be a learning opportunity for us to become better leaders, the whole problem will get solved eventually.
Work , and when you work, work well, no matter what.
