It's one of question which differs from person to person. How do you define richness?
The definition of wealth is relative. In my opinion, people have different views on defining wealth. Materialistically, wealth is defined as lots of money, lots of property, being able to invest anytime and anywhere. For some people, wealth is not always calculated by how much property they have, they define rich in a very simple way. For them, wealth is measured in terms of the health of themselves and their families and having money to finance their family's needs.
Wealth is relative to each individual. It depends on which side you judge the meaning of wealth.
Being wealthy is not the same as being rich. Wealth is like the accumulation of valuables and financial holdings of a person. It could be money, real estate, investments, businesses, valuable possessions, etc. But being rich means feeling like you have enough money to live comfortably and enjoy the things you want in life. In simpler terms, wealth is what you have, while being rich is how you feel about what you have. It's possible to be wealthy but not feel rich if you're not experiencing financial wellbeing, and you can likewise feel rich even if you have a moderate amount of wealth if you're content and satisfied with your financial situation.
