Money in pocket cannot buy all goods and services that we may need to live because there are some things like love,friends,happiness,care,feelings,etc which we can not buy by money and these are some of the things that we need to live very well than anything in the world and to buy this we need to give exactly the same thing we want.
For example: if we'll love some1 in back even he/she would love u,if u care for some1 in back even that person will care for u.
