Hongkongers live long, healthy lives and are generally financially secure.
Despite everything we have, our sense of well-being is often quite low.
This should not be the case when we compare ourselves to others. Think about, for example, the low literacy rate on remote parts of the mainland, the dire malnutrition in Laos, the serious poverty in Ethiopia or the war in Iraq. We are aware of these situations, but not affected by them.
And yet we still don't seem very happy.
Well-being is an abstract idea - it comes from appreciating what you have and realising how lucky you are. It is internal - just because you're rich, you won't necessarily be happy. Someone with just enough money for food and clothes but who is satisfied with their life can be very happy.
Look at your life and realise how lucky you are - and your sense of well-being will increase.
