Importance of "Money"

"Is money the most important thing in today's world?" This is one big question that bugs me all the time and even after thinking a lot i am unable to get the answer for that. Everyone knows that no one can survive without money because it buys food, clothes, shelter and many more things we need to live but is it all that is needed? If a person was alone on this planet with a lot of money with him would he survive? I am not too sure about that but i sure know that money might buy survival but it cannot buy satisfaction and that is the most important thing that is needed to live. A human being would seize to live if he is not satisfied and satisfaction comes not only from money but other things like family, love, friendship etc.
Its hard to describe why all this is important because human mind is very complex. But i have realized the truth is that "Money is not everything".
