A trap is only a trap if you don't know about it. If you know about it, it's a challenge.

This quote means that if you already know something is a potential problem or a threat, you can use it as an opportunity instead. If you are aware of the challenges that may be facing you, you can use them as a way to test your abilities and gain confidence in yourself and your skills. It’s a reminder to stay positive and believe in yourself, which can help you to make the most of any situation.
