"Every man's life lies within the present; for the past is spent and done with, and the future is uncertain."

"Anyone can fight the battles of just one day. It is only when you and I add the battles of those two awful eternities, yesterday and tomorrow, that we break down. It is not the experience of today that drives us mad. It is the remorse or bitterness for something that happened yesterday or the dread of what tomorrow may bring. Let us therefore do our best to live but one day at a time."
