“Strike while the iron is hot,” is an old proverb. It tells us not to miss an opportunity by waiting. When we have a chance to get something done, we should go ahead and do it! This proverb is the same in both Japanese and English. It comes from blacksmithing. A blacksmith puts iron in a fire to heat it and make it soft, then hits it with a hammer to change its shape. If he waits too long, the iron will cool down and he won’t be able to change its shape. It takes a long time to make something, though. The blacksmith has to reheat the metal many times.
