A thought can advance your life in the right direction only when it answers questions which were asked by your soul. A thought which was first borrowed from someone else and then accepted by your mind and memory does not really much influence your life, and sometimes leads you in the wrong direction. Read less, study less, but think more.

Learn, both from your teachers and from the books which you read, only those things which you really need and which you really want to know.
