Translation:The eternal beginner begins eternally.
"Eterna Komencanto" is a term for people who start to learn esperanto but don't achieve fluency or make very slow progress. Basically, people who are in love with the idea of a universal language but don't put forth the massive effort required to learn even a simple language. Sometimes it's derogatory sometimes it isn't
En la komencanta menso estas multaj ebloj, sed en la fakula tie estas malmultaj. http://www.shambhala.com/zen-mind-beginner-s-mind.html
