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.
Do not overlook negative actions merely because they are small; however small a spark may be, it can burn a haystack as big as a mountain.
