If we are talking about the total Truth, it is the eternity desire(pothos) of the human soul. In greek language the word ''Truth'' is called ''Alithia'' and etymologically means ''what can not be forgotten''.
So i believe that once we had met Truth, and our soul can never forget this <<land>>. And the whole journey of life, only has meaning when we are travelling back to this land, with any cost.
The well-being instead, concerns the earthy desires. It is also a choise, but not for the heroes...
