The value of Time

From Lawrence of Arabia. Probably the finest film ever made.

Sherif Ali: There is the railway. And that is the desert. From here until we reach the other side, no water but what we carry with us. For the camels, no water at all. If the camels die, we die. And in twenty days they will start to die.
T.E. Lawrence: There’s no time to waste, then, is there?
