I am quite happy with a house I live in. I suppose I could lose few kg. All in all my health is not ideal but whose really is? I am on the poorer side( I am sure that glasses price is gonna bite my finances even more). But many have even less than me.
The problem is that for most humans there is never enough. So they could already be living ,,a normal'' life and just don't know it. I think that my life is quite normal as it has ups and downs. If it was much better than it is it would not be normal. It would be pretty damn awesome.
I am yet to meet a single person who is completely content in this life - there is always something they want. It isn't always something material, but there is always more to have.
Most people are on the poorer side - on average. They have to be when less than 10 people own more wealth than the bottom 50% of the world.
