Are some people inherently born happy whilst others are hard wired to be moody? Apparently the constitution of a person's brains do contribute to some extent whether a person is optimistic or not. Good feelings are experienced in the left frontal cortex and bad feelings in the right. It seems that people with a happier disposition have more activity in the left frontal lobes. This explains why some babies are more fretful than others even in the same environment.
Fortunately with the understanding of neuroplasticity it is now known that we can change our brains by changing how we think and feel. Basically the way we behave, think and emote shape the neural pathways and synapses.
Given this good news how do we then psycho ourselves? It may be very easy to tell someone to think positive but bad habits die hard. When the Dalai Lama was once asked to recount the happiest moment of his life, he replied without hesitation "Now". But we are not the Dalai Lama or brought up the way he did. Yesterday a talk I heard over podcast shed some light as to why we can never (like the Dalai Lama) hold on to the belief that "Now" is the happiest moment. The hindrance basically lies in our perpetual "attachment to how things should be". So if I wake up in the morning and realise I run out of bread, my attachment to a normal breakfast of toasted bread may cause some irritation. Of course I can blow it up further by berating myself for forgetting to buy or scold someone who is supposed to see to it. This is just an example when minor things go awry. Needless to say there are bigger issues affecting health and family that are more difficult to accept and that "attachment to how things should be" become more severe and pervasive. In no small measures are these affected by social/cultural norms and peer pressure. A well interconnected world in the like of facebook plus subliminal advertising (manipulating our unconscious mind) also help shape our concept of "how things should be". So even when we fall sick we blame ourselves for not taking good care of our body, not exercising enough or not taking sufficient health supplement to keep ourselves in tip top condition. Needless to say the "should be"s extend to our family members, our expectations of them to be at least in line with the norm. The list goes on.
Ironically the most fearful rejection of "how things are now" is the inability to accept our feelings. This suppression can have serious consequences psychologically. Some people, for example, are brought up in an environment where feeling angry is disapproved. Anger is hence repressed and often results in depression. The happy faces in facebook and the "all-is-well" front we see everywhere also tell us that if we feel sad something is not quite right with us or we make others uncomfortable when we are sad. If you have watched Disney's pixar movie "Inside Out" you will know what I mean. In the show "Joy" was trying to run the main character's life and blocking out "sadness" to the detriment of her authentic self and almost landing her into numbness and depression.
As someone once said "Life is like a piano; the white keys are happy moments black keys are sad moments
