One might think they are doing the best they can, however in the eyes of others are they? You always wonder if your efforts are truly making a difference or could you work harder. Even the people who are at the top of their field wonder am I giving it my all. Doing the best you can should be all anyone should expect even though they might not deserve it.
You also wonder if the people who give raises and opportunity are seeing you do your best when it counts the most. Praise is always good in this situation.
Sometimes we all wish others would give their best because so much of the burden is carried by ourselves. Without our best nothing gets accomplished. We all have to make things happen in all facets of life but there are times when we don’t want to do the best we can because we are just tired of it all.
