Even on my FB newsfeed I can see the difference between those who are pursuing extrinsic happiness and those those who are developing intrinsic happiness.
Extrinsic happiness is tied with titles, academic achievement, professional advancement, pursuit of money to buy the perfect house, marry the perfect person, have the perfect kids.
Intrinsic happiness comes from spiritual wholeness, confidence in self, resting and reflecting.
The difference between the two is stark. And I believe will make all the difference 2, 5, 10, 25 years down the line and even for eternity.
