The foregoing are but glimpses of the opportunities for observation out of which I draw my deductions relative to profitable living. Four complete trips around the world--two of them before the time of ocean steamship lines and continental railroads; thirty-six trips across the American Continent by various rail, water and stage routes; sixteen voyages across the Pacific Ocean, and many across the Atlantic; intermittent periods of residence in many different countries of Europe, in China, in India, in Japan and in different localities in the Americas; as well as visits to parts remote from the lines of travel, such as South Africa, Yucatan and the mountain regions of Mexico and Central America, that are the type of all of the South American countries; and all of which residences and visits have been chosen at times of greatest interest in each locality; in response to the invitation of the Spirit-of-Adventure by which I have been led--these, together with no less than thirty-eight distinct occupations, embrace the sum of my opportunities. Fortune has always been kind to me when I have trusted her; when my aims and ambitions were worthy, and when I have been sufficiently appreciative and grateful for the things I already possessed to merit and invite continued favors; but, she has always passed me by whenever I have doubted her goodness or questioned her intentions. And so consistent has been the course of Fortune, as viewed in the retrospect, that I can assert, with all the assurance of firm belief, that "Unto him who hath (appreciation and gratitude) shall be given; but unto him who hath not (appreciation and gratitude) shall be taken away even that which he hath." Until I began to collect my remembrances into groups, form them into classes for review and deduct from them suggestions for profitable living, I had thought that my chronic restlessness was aimless as measured by the common estimate of usefulness; but the sympathy aroused by the publication of my little volume--first, privately printed,--_Menticulture, or the A-B-C of True Living_--revealed the possibility of utilizing my varied experiences and observations to good advantage in calling attention to uses-of-energy, points-of-view, habits-of-thought and habits-of-action, that made for happiness in some persons in some parts of the world, while they were entirely unknown to others as well fitted to enjoy them.
