when if ever is the sacrifice appreciated?

as parents we have to make decisions/sacrifices that often cost us and those we love all for the greater good.

time spent together, one on one is sacrificed and i'm left wondering if it we will ever be able to recover from it.  and in addition i'm left to wonder if the greater good is really all that much greater.  for the greatest thing to me is time with the ones i love the most.  and that time is fleeting away.
