This book is sent out to induce people to look at their own eyes, to pick up the gold in their laps, to study anatomy under the tutorship of their own hearts. One could accumulate great wisdom and secure fortunes by studying his own finger-nails. This lesson seems the very easiest to learn, and for that reason is the most difficult. Russell Conwell (1843-1925) was an American Baptist minister, orator, philanthropist, lawyer, and writer.
