"知道自己不知道什么比出类拔萃更有用。"

Simplified Meaning:

Understanding that there are things you don't know can be more helpful than being very smart. For example, imagine a doctor who knows they have limitations and asks for help from other specialists when needed. This doctor can provide better care to patients than one who believes they know everything and never seeks advice. Admitting when you lack knowledge or skill lets you learn from others, make better decisions, and avoid mistakes. This attitude helps you grow and improve because you stay open to new information and different perspectives. Applying this mindset in your life means not being afraid to ask questions or seek advice, which can lead to more success and fewer problems. For instance, if you're building a piece of furniture and get stuck, it's better to ask for help or look up instructions rather than stubbornly trying on your own and possibly ruining the project.
