+ 342 Life is as if you were traveling a ridge crest. You have the gulf of inefficiency on one side and the gulf of wickedness on the other, and it helps not to have avoided one gulf if you fall into the other. Theodore Roosevelt

+ 328 Inefficiency is a curse; and no good intention atones for weakness of will and flabbiness of moral, mental, and physical fiber; yet it is also true that no intellectual cleverness, no ability to achieve material prosperity, can atone for the lack of the great moral qualities which are the surest foundation of national might. Theodore Roosevelt

+ 218 Efficiency is as essential as patriotism; one is useless without the other. Theodore Roosevelt

+ 378 So we find that the three possible solutions of the great problem of increasing human energy are answered by the three words: food, peace, work. Many a year I have thought and pondered, lost myself in speculations and theories, considering man as a mass moved by a force, viewing his inexplicable movement in the light of a mechanical one, and applying the simple principles of mechanics to the analysis of the same until I arrived at these solutions, only to realize that they were taught to me in my early childhood. These three words sound the key-notes of the Christian religion. Their scientific meaning and purpose now clear to me: food to increase the mass, peace to diminish the retarding force, and work to increase the force accelerating human movement. These are the only three solutions which are possible of that great problem, and all of them have one object, one end, namely, to increase human energy. When we recognize this, we cannot help wondering how profoundly wise and scientific and how immensely practical the Christian religion is, and in what a marked contrast it stands in this respect to other religions. It is unmistakably the result of practical experiment and scientific observation which have extended through the ages, while other religions seem to be the outcome of merely abstract reasoning. Work, untiring effort, useful and accumulative, with periods of rest and recuperation aiming at higher efficiency, is its chief and ever-recurring command. Thus we are inspired both by Christianity and Science to do our utmost toward increasing the performance of mankind. This most important of human problems I shall now specifically consider. Nikola Tesla
