The meaning.... who the heic knows, we are generally bred as robots, hell, as soon as we can speak we are moving swiftly into creche to be educated, to be sent to school, to college, to work, to pension, to casket. The only time you can truely enjoy life is when you retire and that is when life has left your body, for most.
So maybe there is no meaning, everybody goes through the above routine in a different way. Survival of the fittest I suppose, any animal on this planet is here to breed, survive. Humans are the only animals on this planet that are greedy. What we want is to breed, survive but with plenty of money, which is what generally drives us all to be slaves, work...circle of life as Elton John would say. What you do inbetween, fair play, that's your business.
