"如果我早知道，我会成为一名锁匠。"

Simplified Meaning:

The quote is saying that if the person had understood something important earlier, they would have chosen a simpler or more profitable job, like being a locksmith. Many times in life, people realize too late that there are easier ways to achieve their goals, or they see others doing well in jobs they had not considered. For example, imagine someone who struggled for years to make a living as an artist. They faced difficulty in selling their paintings and spent long hours working on their art. Then, they meet an old friend who became a locksmith. This friend has a stable income and a stress-free life, and sometimes even helps the artist by fixing their locks for free. The artist wishes they had known earlier that a simpler job, such as locksmithing, could provide a good, stable life without so many struggles. This teaches us to look around and learn from others' experiences before making major decisions. It can also mean that sometimes, simpler jobs can be as rewarding as complex or glamorous careers. People should keep an open mind about different opportunities and not overlook the value in straightforward, practical work.
