I remember reading an article about happiness some time ago. It identified many criteria that those with a generally happy disposition tended to have.
There were not many surprises. It stated, for example, that severe poverty can have a negative impact on happiness but once all basic needs are met, there is no correlation between increased wealth and an increase in happiness (although many strive for wealth, I assume, with the idea it will make them happier which is not surprising considering the conditioning we receive in the capitalist western world!). It spoke about 'flow', personal 'wiring' and health and so on.
However, the one happiness criteria that stood out for me was, 'the ability to transcend pettiness.' It is remarkable how we can sometimes let something that is, in the large scheme of things, quite insignificant, annoy or upset us to the point of it being detrimental to our happiness and wellbeing.
Which brings me to one of my more serious catchphrases. When a storm kicks off in a tea cup, I will admit, I can become embroiled - like many - I suspect. However, I can find the exit when I re-guage with the thought, 'some parents watch their children die in their arms from starvation.' It's usually all I need to put things back into perspective and feel humbled by my own stupidity!
