What does a person really need? Shelter, yes. And clothing. Food and water too. Friends and company.
Anything more is superfluous, and even these basic necessities can be abused. Does a man really need a three-storey, ten room mansion? Does a woman need gourmet food every night? Are children naked without the most expensive brands of clothing?
The answer is obvious. What is not obvious is why, knowing all this, you choose to waste your money of what is not needed, sacrificing your security and peace of mind for something that can easily be taken from you by a thief.
Why do you surrender what is in your control to gain what is not?
