Che Guevara Quote
You should fight to be among the best in school. The very best in every sense and you already know what that means; study and revolutionary attitude. In other words: good conduct, seriousness, love for the revolution, comradeship. I was not that way at your age but I lived in a different society, where man was an enemy of man. Now you have the privilege of living in another era and you must be worthy of it.
