A great estate is a great disadvantage to those who do not know hot to use it, for nothing is more common than to see wealthy persons live scandalously and miserably; riches do them no service in order to virtue and happiness; it is precept and principle, not an estate, that makes a man good for something.
I cannot teach you the ten principles of service. But a little child and a thief can show you what they are. From the child you can learn three things: He is merry for no particular reason; never for a moment is he idle; when he needs something, he demands it vigorously. The thief can instruct you in seven things: He does his service by night; if he does not finish what he has set out to do, in one night, he devotes the next night to it; he and those who work with him love one another; he risks his life for small gains; what he takes has so little value for him that he gives it up for a very small coin; he endures blows and hardship, and it matters nothing to him; he likes his trade and would not exchange it for any other.
There is no such thing as a "self-made" man. We are made up of thousands of others. Everyone who has ever done a kind deed for us, or spoken one word of encouragement to us, has entered into the make-up of our character and of our thoughts, as well as our success.
The first real mental illumination I remember to have experienced was when I saw that the universe exists in each of its individual atoms - that is, the universe is the result of a few simple processes infinitely repeated. When a drop of water has been mathematically measured, every principle will have been used which would be called form in the measurement of the heavens. All life on the globe is sustained by digestion and assimilation; when by voluntary and traumatic action these stop death follows. The history of an individual mind is the history of the race. Know one thing in its properties and relations and you will know all things.
