I have thought about it a great deal and always am confused. After a big chain of logical inferences I arrive at the result: there is no measure for 'enough'. It is a relative term.
So is beauty, money, power, intelligence,love--- all relative terms
Now is there something we can all say is not relative but is absolute in this world?
Maybe not, because our existence itself is governed by so many metrics! So what to say of a particular dimension of existence like love, beauty etc? eh??
