A man sentenced to death obtained a reprieve by assuring the king he would teach his majesty's horse to fly within the year - on the condition that if he didn't succeed, he would be put to death at the end of the year. "Within a year," the man explained later, "the king may die, or I may die, or the horse may die. Furthermore, in a year, who knows? Maybe the horse will learn to fly." My philosophy is like that man's. I take the long-range view.
Peace is never long preserved by weight of metal or by an armament race. Peace can be made tranquil and secure only by understanding and agreement fortified by sanctions. We must embrace international cooperation or international disintegration. Science has taught us how to put the atom to work. But to make it work for good instead of for evil lies in the domain dealing with the principles of human dignity. We are now facing a problem more of ethics than of physics.
Get to know yourself. Know your own failings, passions, and prejudices so you can separate them from what you see. Know also when you actually have thought through to the nature of the thing with which you are dealing and when you are not thinking at all... Knowing yourself and knowing the facts, you can judge whether you can change the situation so it is more to your liking. If you cannot--or if you do not know how to improve on things--then discipline yourself to the adjustments that will be necessary.
Colleges don't teach economics properly. Unfortunately we learn little from the experience of the past. An economist must know, besides his subject, ethics, logic, philosophy, the humanities and sociology, in fact everything that is part of how we live and react to one another.
Learn to take losses quickly and cleanly. There is something about inside information which seems to paralyze a man's reasoning powers. Beware of barbers, beauticians, waiters - or anyone - bringing gifts of 'inside' information or tips. Don't try to be a jack of all investment. Stick to the field you know best.
Recipe for success: Be polite, prepare yourself for whatever you are asked to do, keep yourself tidy, be cheerful, don't be envious, be honest with yourself so you will be honest with others, be helpful, interest yourself in your job, don't pity yourself, be quick to praise, be loyal to your friends, avoid prejudices, be independent, interest yourself in politics, and read the newspapers.
Approach each new problem not with a view of finding what you hope will be there, but to get the truth, the realities that must be grappled with. You may not like what you find. In that case you are entitled to try to change it. But do not deceive yourself as to what you do find to be the facts of the situation.
