Could not agree more. Our definition of happiness often includes "Success". And people's definition of success is quite relative, depending on other people's current perceptions and ideas of how we should be or what people envy, or image.
I retired 6 years back, spend more time sitting and walking in parks, feeding and playing with stray dogs, and remaining in the present moment. I've never been happier. Others see mine as a life wasted - dropping a high paying job, loads of money to spend, and becoming a miserly bum !
