Said the maggid to Rabbi Zusya, his disciple: “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 slight 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.”
