I am a student of knowledge and I have thirst and love for knowledge but one day suddenly my thirst for knowledge have been lost and I lost interest at learning anymore
I'm confused about what is the true purpose of knowledge, in my mind knowledgeable and ignorant person is the same in their own sense(its just my thoughts) and in my mind it's fine to be ignorant and I don't know what's happening. How can you convince me to seek knowledge, what is the true purpose of knowledge

I would highly recommend you to read this book especially the introduction.
