Sometimes I Wonder...

Will it really matter if there are dusty bookshelves when I die?  Will God hold that against me?
Do we all start over in Heaven?  Will it matter if I have a degree or what I have accomplished on earth?  I don't think so.  I think it is all like chaff that will burn away.  I truly believe the ONLY thing that matters is our relationships. With God and with others.   So many times I find myself asking "will it matter?" and that leads to the question how much in this life is really useless?
