The secret is to maintain ones sense of wonder. The purpose of life, if it could be said to have one, is to see. To experience your time here. It took me over forty years to be able to look to the stars and really believe what I am seeing. No one could ever imagine anything so awe inspiring as reality. We are not here long, so savour each moment, even the bad ones, because there was a lot if nothing before you opened your eyes and there will be a lot more once they close once more.
