The three practical rules, then, which I have to offer, are, --/ Never read a book that is not a year old./ Never read any but the famed books./ Never read any but what you like.

Nature is what you may do. There is much you may not do.

When nature has work to be done, she creates a genius to do it.

As to methods, there may be a million and then some, but principles are few. The man who grasps principles can successfully select his own methods.

Henceforth, please God, forever I forego the yolk of men's opinions. I will be light-hearted as a bird and live with God. I find him in the bottom of my heart, and I hear continually his voice therein.

The only prudence in life is concentration.

The primary wisdom is intuition.
