Shoshin (初心) is a word from Zen Buddhism which means “beginner’s mind”. It refers to having an attitude of openness, eagerness, and lack of preconceptions when studying a subject, even when studying at an advanced level, just as a beginner in that subject would. (Wikipedia)
The beauty of realizing that you know next to nothing is the beauty of realizing that you will never know everything. I think the thirst for knowledge is what keeps the demons at bay.
