3.Unrealistic expectations Our expectations serve us like a yard stick where we kind of measure people both ahead of time and after an event. You think you know what to expect of others and yourself, therefore, you check to see if all of that expectations are missed or met. What happens when your expectations are continuously missed? You turn grouchy, to start with. If your expectations are continually abused, it can become the catalyst of unrest and great unhappiness. We hate to be disappointed. The question is - Are your expectations realistic? It's good to be good, but it's annoying to work with someone who wants to be perfect. Besides, it's just not possible, so you could be unrealistic and also be a real pain in the backside.
