Even as the stone of the fruit must break, that its heart may stand in the sun, so must you know pain.
And could you keep in your heart the miracles of your life, your pain would not seem less wondrous than your joy;
And you would accept the seasons of your heart, even as you have always accepted the seasons that pass over your fields.
And you would watch with serenity through the winters of your grief.
Kahil Gibran The Prophet
I frequently say to people I work with that one of the key things is how we deal with 
disappointment. It is a necessary skill, because it is a frequent and inevitable occurance in an imperfect world. Each one of us has our own way of working with the discomfort coming from disappointments in our plans or in other people. These ways are often based on how well our parents helped us deal with early shocks and disappointments, or whether they tried to shield us from the ups and downs of reality. Sometimes a parent can think that the best way to raise their child is to shower them with protection and insulate them from moments when they or the world are less than perfectly loving. However, the child has to learn to live in the real world, and the real world isn’t perfect. In other words, it is right – and leads to the development of a healthy psyche – that the child is gently disappointed and comes to understand that it is not always possible to have people around them who understand and respond perfectly to their every wish. Even from an early age we have to learn to share, take our turn in games, postpone our own gratification and acknowledge that other people have needs, moods and different agendas.
Rather than a parent having to being perfect all the time, English Psychotherapist Winnicott said that they just had to be “good enough”. This means that the parent provides enough support – or “holding” – to support the child without going to the extremes of stifling it or of abandoning it. The skill of the “good-enough parent” is to give the child a sense of loosening when faced with new situations rather than the shock and subsequent fear of being ‘dropped’. This allows the child develop resources, maintain a sense of control and stops them from feeling that the world is unsafe all the time.
If this happens successfully, the challanges of life do not frighten because the child builds up interior resources. It means that relationships does not threaten because, paradoxically, a smothering early closeness can trigger fears of engulfment in later life. And it means that the adult has a healthier structure for dealing with disappointment because as a child he or she has learned that life and people can not be perfect all the time. Often our disappointments do not arise so much from what actually happened, but more from how we compare what happened to our expectations, our inner patterns or our fixed version of reality. Disappointment show us that life – like the good enough parent – is not always available to us in the fixed way we want or whenever we demand it, but is still good despite that.
For this reason disappointments are good teachers. They allow us to see that there is more to us than our conscious thoughts and desires. They reveal how we can be attached to a specific version of how things should be, or of what life owes us. This does not mean they are easy because trying to avoid what disappoints is deeply ingrained in the human psyche. However, we grow more quickly if we are open to working with disappointments rather than avoiding them. Rather than being negative, they can become positive moments of growth, leading us away from the suffering which is based on our lack of understanding of the deep reality of change.
Our culture has evolved into one that is pleasure-based and ego-identified, and that emphasizes immediate gratification. It also began to define success as your ability to control outcomes. Today, we teach our children that if you are an effective person, you can control your life. You can get and do what you want. If you do, you win in life. This modern image portrays “winners” as people who have it all together. You are not supposed to have internal conflicts, stress, or anxiety—that means you are incompetent. …… But this perspective flattens life. It denies the possibility of finding a deeper meaning to your experience. If you measure your self-worth and effectiveness according to these superficial cultural standards, then each time you suffer you are forced to interpret suffering as humiliation. Why would you choose to acknowledge suffering if it only stands for failure?
Phillip Moffitt, How Suffering got a Bad Name
I am reading some books by Stephen Levine. He has worked extensively with those who 
are dying, and writes about grief and loss. What he has found is that many arrive at the end of their life with regrets, wishing that they had done this or that, lived more fully here or there, realized their potential in this way or that. This has led him to emphasize living each moment fully, not limiting ourselves in this moment to our past or waiting for our future, in order to have no regrets:
Most of life only lasts a moment. Then our life becomes a memory, a dream. We are only alive a millisecond at at time. This moment! Or as one teacher put it, holding his thumb and forefinger about a quarter inch apart, “All of life is only just this much–just a moment in time.” When we open to this very instant in which awareness produces consciousness, we are fully alive. Completely preent. Big-minded.
To the degree we are present for “just this much” this living moment, we are alive. Otherwise we numb to the vibrancy and beg upon our deathbed for one more chance.
Most think that living a “full life” means living into old age. But if you are not alive this moment, what makes you think you’ll be alive then? To live fully is to be filled with this moment. Present for this millisecond, this day, this week, this life.”
Stephen and Ondrea Levine, Embracing the Beloved
In this he echoes the words of Daniel Gilbert in his book Stumbling on Happiness. He too draws attention to not neglecting to do the things we want, to dare to choose certain paths that open up in front of us.
... most people think they will regret foolish actions more than foolish inactions. But studies show that nine out of ten people are wrong. Indeed, in the long run, people of every walk of life seem to regret not having done things much more than they regret things they did.
Traditionally, in the Christian yearly calendar, November is the month for remembering those who have died.The roots of this tradition are probably found in the basic human awareness of the approach of winter and the shortening of the days. As well as reminding us of the impermanence of all things, including our health and life, it helps us reflect on the other losses which we face at times in our lives, such as when faced with change, or sickness or having to move. The most basic practice in these moments is to be aware of the feelings these losses provoke and not to run from them.
“On some basic yet very deep level all of us feel fundamentally alone, and until we face this directly, we will fear it. Most of us will do almost anything to avoid this fear. Many, when faced with the fear of aloneness, get extra busy, or try to find some other escape. Ultimately, however, the willingness to truly feel the fear of aloneness and loss is the only way to transcend it. It’s also the only way to develop intimacy with others, because genuine intimacy can’t be based on neediness or on the fear of being alone.”
