Saltier than Carthage (if it had been salted)

Explanation: Caesar (yes, THE Caesar) is said to have wept at a statue of Alexander the Great, because, at 33 (the same age Alexander had died at), Caesar had no great accomplishments to his name, and felt that he was pathetic by comparison.

Caesar would later become one of the most influential individuals in world history.

Always remember - it's not too late. You aren't a failure.
