Work is a great discipline

Take a very amusing instance: you want to fill a bottle from another bottle; you concentrate (you may try it as a discipline, as a gymnastic); well, as long as you are the bottle to be filled, the bottle from which one pours, and the movement of pouring, as long as you are only this, all goes well. But if unfortunately you think at a given moment: “Ah! it is getting on well, I am managing well”, the next minute it spills over! It is the same for everything, for everything. That is why work is a good means of discipline, for if you want to do the work properly, you must become the work instead of being someone who works, otherwise you will never do it well. If you remain “someone who works” and, besides, if your thoughts go vagabonding, then you may be sure that if you are handling fragile things they will break, if you are cooking, you will burn something, or if you are playing a game, you will miss all the balls! It is here, in this, that work is a great discipline. For if truly you want to do it well, this is the only way of doing it.
