Measuring Success

Success is something that everybody in this world craves for. But how would you measure success? Who has the yardstick or do we create our own yardstick? Does success mean that we want nothing more or is it just a relative and transiet term.
Sometimes the soceity enumerates the criteria based on which an individual's success is measured just as in India, rural if not in the urban. In other places it is the individual who defines it just as in the western countries.
If we have all the wealth, education but no peace of mind does it still mean that we are successful in life. Or let us say we are working on the latest invention but our relation with our kith and kin who matter most to us is nill, does that consitute to our success.
We want something or other through out life so we can never say that we are truly successful. I know that next thing you would say is look at it from a philosophical point of view and then both success and failure are part and parcel of life. But this is far from philosophy.
Well, I have done my job if I have either confused you or if you have read the whole post and found that I have just blabbered. :-)
