Principles

Of Humanity;
Confucius said; "Do not do to others what You would not want done to Yourself."  
The Christian Golden Rule says; "Do unto others as You would have them do unto You."
The principle in both is the same.  

Of Wealth;
Pay Yourself first!!!
No matter how much a person makes, the tendency is to always spend whatever it is You make.  If You always put at least ten percent of whatever You make into a savings account before it gets spent elsewhere, You will always have enough money.
Confucius put it a little differently, but the principle is the same.  He said; "If those who produce wealth do so rapidly, and those who spend wealth do so slowly, then wealth will always be sufficient."

If sincerely practiced, these two basic principles can provide a solid foundation for Life.
