I think the older we get, the more we reflect on our lives and how we've lived them.
Some wish they'd seen more, helped more, loved more, cried more and believed more...others are just glad that's it's over and they can finally rest.
Maybe that's why we question our faith as we age...worried that we may have devoted our whole lives to something fruitless....but in the end we are all dust and I truly feel that as long as you are remembered by loved ones...your life can never be fruitless no matter what course you chose.
