This thought entered my head last week during the course of a project. Whilst not true 100% of the time, let me try to explain what I was thinking. As a professional you do a certain job to a certain standard. Your aim is to always meet that minimum professional standard, not only in the *actual* work, but in all aspects of how the work is done; how you communicate with your clients, how you listen to them, and how you bring them along with you. Occasionally (as happened to me last week), something happens that makes you either question your professionalism, or reinstate its fundamental tenets. When such situations arise, as a professional all you can really do is continue to be, well, professional. So, one can't worry. It is futile to do so. For one has carried out one's duties in a professional manner, and the results are those that would be obtained by any professional given the same circumstances. There is little more to be said.
