Have a plan of study, but study beyond the plan. Let the teacher address each point as a question to his own mind, and think till he gets an answer - and an answer that is true. Do not deny yourself the help of good books on the subject of your lessons. Borrow the minds of the best thinkers, at least to set your own thoughts going, but do not read without deep and original thinking. If possible, talk your lesson over with an intelligent friend.
Collision often brings light.
Our discussion would be incomplete without some mention of the frequent violations of the law. The best teacher may spoil his most careful and earnest work by careless blunders. The true teacher will make as few errors as possible and will profit by those that he makes. The secret of success is to make no mistakes. The ignorance of a teacher s students often tempts the teacher to neglect all preparation and study or to neglect careful preparation and study.
