Flourishing. That’s the new term Martin Seligman, father of positive psychology, has crafted to supersede ‘Happiness’. You can read all about it in his book of the same title. In a nutshell, the five elemnent s to cultivate are as follows:
Positive emotion – the pleasant life is what we instinctively think of when asked about increasing happiness. It is a cornerstone of well-being theory but only one of five separate elements.
Engagement – also known as ‘Flow’, the feeling of time stopping, so engaged are we in what we are doing.
Meaning – belonging to and serving something you believe is bigger than yourself. This can be religious or secular, really big or just a stretch beyond yourself.
Accomplishment – pursuit of achievement and mastery for its own sake
Positive relationships – other people turn out to be the best antidote to the downs of life and the single most reliable up.
I recommend his book - this is backed by hard science not pop psychology.
