There are advantages and disadvantages to really looking forward to an event, or a meet up with a good friend, of which, some of the advantages are represented by just the anticipation of all the good things that are going to occur, as well as the anticipated enjoyment that we will get from the event or meet up. On the other hand, the disadvantage of being overly excited about an event or meet up is that things may not even come close to the great expectations envisioned, and the further away we are from what we were anticipating, the greater will be that disappointment. This is why we need to be mindful about our expectations, especially when an event or meet up is not wholly in our control, which is often the case, because things happen, and not everything that happens is going to be good, and when that is the case, we typically feel disappointment, and for some people, that disappointment lays heavy upon them.
That said, it isn’t like it’s wrong to feel disappointment, but it’s wrong when we allow such disappointment to overwhelm us, without understanding, that life has its unexpected and unanticipated challenges, that we are going to need to adjust to, or else, we will find ourselves suffering disappointment more often than expected, because the world does not revolve around us, and further to the point people and the societies have their own expectations to be met, which may not mesh up well with what we have in our own mind.
Indeed, to believe that the happiest life is the life in which everything goes our way and according to our plans, may seem to make eminent sense, but since that isn’t the way that society works, we need to recognize that as much as we might have high expectations about this or that, we need to temper such with the acknowledgment that the more important thing is that we do our level best with what we have to work with, and that we not get so fixated in our mind and thoughts that we can’t adjust to what needs to be adjusted. For a certainty, those who truly comprehend that life is a two-way street are going to do better with dealing with the vicissitudes of life, as compared to those who believe that life is always going to be smooth sailing.
It is good to have goals, and it's good to have expectations about events that have yet to come to fruition and are highly valued. Whether or not things go as anticipated, or perhaps even go better, is something that is unknown until it becomes known, and may well be subject to the input that we bring, as well. While it is true that none of us will ever have all of our expectations met, the more important thing is how we deal with adversity and disappointment, in which, those of maturity and vision, will learn from such experiences and become better for it, and those lacking good character and sensibility, will rue the day, seemingly unable to ever let it go.
