This old saying uses imagery of a blacksmith and his art. If the blacksmith doesn’t strike the iron when it is hot and flexible, the metal will soon cool and harden, thus creating a lost opportunity, but if, on the contrary he “strikes while the iron is hot,” he will maximize his efforts and reap greater rewards faster.
In business, if sales are going well, you might work extra hard in order to “strike while the iron is hot.” A related expression is, “make hay while the sun is shining.”
