I think your comment put my writing very much in the human and the personal terms for people to understand
The most painful thing to realize is your own limitations and that you cannot have everything
And sometimes limitations such as location, profession and look as well as skills plays a big part
I think what makes people so unhappy is the modern world it makes life too hard
If you read about people in the middle ages their life was brutal with death around the corner but the people lived
They had fun and had relationships now people are incredibly isolated and behave like robots
