Money is essential to mankind because without money, we can not afford our needs in the markets. No matter how self made you maybe, at your homes or respective places, you will still be in need to others made as long as you live in this developed generation unlike past generations that lived primitively of underdevelopment with no experiments of technologies.
In this era, money is necessary but everyone can not be rich or wealthy and we it is not encouraging to go extra mile just to make to make the wealth even when our portfolios could afford us with our essential needs.
We just have to be contented with what we have but knowing that our savings in the banks without incomes is not enough to keep us going a long time because it will finish one day that we can not even afford the least any longer.
So. Even while we are rich, wealthy or poor,  we still need to make more money for our future needs.
