This saying was evidently born in a blacksmith’s shop. It has done service in every kind of shop, and has passed into one of those proverbs which are as often false as true. Indeed, this is the character of the greatest number of proverbs. True in a limited and special range, they are used as of universal application. Now, though a man may have “too many irons in the fire,” it is just as true that he may have not enough irons in the fire. It is foolish to take on more work than one can do well. It is wicked to work so excessively as to exhaust the strength, weaken digestion, impair sleep, and shatter the nervous system. When these results are produced by an inordinate use of the passions, they are called dissipations. But they are none the less dissipations when they spring from an inordinate addiction to business.
But it is not in this direction that men are said to have too many irons in the fire. When a man is carrying on so many separate enterprises that he must neglect some of them wholly, and can attend to none of them thoroughly, he is properly said to have too many irons in the fire. But the same phrase is applied to a man who turns his hands to many different kinds of trade. It is the serious belief of many that a man can not be a good workman in more than one art; that, if a workman means to be skillful, he must devote his life to a single trade, and in confirmation of such notions proverbs fly thick—”Jack of all trades and good at none,” being a specimen!
