It is all about your financial in studying? Please explain, do you mean that you need help financially so you can get a college education or continue your education?
There are many different ways to obtain money for furthing your education, you can apply for scholarships, government grants (Pell grants) which don't have to be repaid, low interest loans where you can't be turned down but you have to repay after you get your degree (Stafford Loans).
Contacting the richest man or woman in the world isn't as easy a task as you might think because they probably get thousands and thousands of requests for financial help daily and if they helped everyone who asked, well they wouldn't be the richest man or woman in the world for very long.
For information on Federal Pell Grants (Financial Aid from the US Government) go to the following website and fill out the forms and apply:
