"表演是最微不足道的才能，也不是一种很高雅的谋生方式。毕竟，秀兰·邓波儿在四岁时就能做到这一点。"

Simplified Meaning:

The quote means that acting isn't as special or important as many people think. This suggests that even a very young child, like Shirley Temple, was able to do it and become successful. It implies that acting doesn't require as much skill or talent compared to other jobs or professions. For example, being a doctor or an engineer is seen as more challenging because it requires a lot of learning, practice, and expertise. The quote is saying that anyone, even a small child, can act if given the chance. If someone wants to apply this idea to their life, they might focus on developing skills in areas that are more valuable and seen as more difficult. They could pursue education and training in fields that require more dedication and hard work. For instance, gaining expertise in technology, science, or medicine could potentially lead to a more respected and rewarding career. In this way, they might prioritize their efforts in areas that people consider as more demanding and higher-status.
