Who is Euripides? Seems like a man of little words, but his famous quote holds so much truth with just four little words! (Also, he certainly was not a man of little words... he wrote SO many plays and such.)
"Much effort, much prosperity."
Euripides was one of the most influential dramatic play writers in classical Greek culture.
He was the author of the only satyr play to survive intact into the modern age, and he even wrote the ode for the Olympic Games, that, unfortunately did not carry through to modern times.
So, he's credible enough to consider his words. :)
