"Prometheus is reaching out for the stars with an empty grin on his face"

This quote by Arthur Koestler is a metaphor for ambition and striving for achievement. Prometheus is a figure from Greek folklore who is known for taking fire from the gods and providing it to humanity. By connecting for the stars, he is symbolically grabbing achievement and success. The empty grin on his face could represent the happiness of striving for something greater, however also the unpredictability of the outcome. It could likewise represent the concept that aspiration is often a lonesome journey, as Prometheus is alone in his pursuit of the stars. Eventually, this quote is a reminder that aspiration is a tough but fulfilling journey, and that it is necessary to stay concentrated and determined in order to attain success.
