The picture above is of our home library.  Lots of books and little room left to house them.  Pretty inexpensive to build due to free review copies from publishers, used bookstores, garage and library sales.  

I am sobered every time I study there because it is a quiet reminder of my great limitations.  At 56, there are many I want to read, but time will most likely run out no matter how much of it is left.  And then there are all the books I want to reread!

So pay attention.  Your reminder of your finitude may not be a library, but there are other things.  And pray Ps. 90:12!
