How To Analyse People On Sight

This book is pragmatical, not philosophical; a practical
manual, not a treatise upon theories. It is intended for the
men and women whose most pressing need is for money;
who wish to get rich first, and philosophize afterward. It is
for those who have, so far, found neither the time, the means,
nor the opportunity to go deeply into the study of
metaphysics, but who want results and who are willing to
take the conclusions of science as a basis for action, without
going into all the processes by which those conclusions were
reached.
