There is nothing wrong with ambition of course. Without it, your life is nothing. But chasing external achievements exclusively will not turn out well over the long term. Ambition to become a bigger, better, more productive, able, dynamic, happy, healthy, valuable person who means more to others is a higher path.
External achievements and material possessions come with it, but they are the side effects, not the target.
How true?How easy it was to confuse self worth with net worth.
Enlightenment is the key.
