I love the part of mental and physical poverty because that's the most common that we can relate to; one must guide his thoughts and understanding of life less he developed a misplaced priorities and confiscate the state of his mind which may lead to mental poverty.

Poverty is not determined by scarcity of things around a man, poverty is a mindset that is characterized with sadness and unsatisfaction over ones life.
That's why you see men that has less yet they live more fulfilled life than they that had it all.

Cultivating confidence and contentment is best for every man irrespective of his GDP.
From my view:
Poverty and richness is as a man determined to see himself.

Thanks a lot @masterwriter
