There is a beautiful poem by Robert Frost which I read at some time in my childhood years. I have always remembered the beautiful lines – The woods are lovely, dark, and deep, but I have promises to keep and miles to go before I sleep. The never stopping, never retreating, just the will, persistence and courage to go on and on. Now, I guess that explains why I sleep late at night, doesn’t it? lol

Whose woods these are I think I know.
His house is in the village, though;
He will not see me stopping here
To watch his woods fill up with snow.
