What is the number one rule in nursing?

I had nothing to do during the weekend, so I browsed on the Internet and found a lot of rules for writing about nurses. Some of the rules were five rules for nurses that must be followed, and some were seven rules that cannot be missed. To me, which one is the most important rule for nursing?

Some people said the top five nursing rules respect unofficial boundaries; often related to personal spaces or equipment usage. Adapt to your coworkers. Asking questions and ect. These rules exist in every healthcare setting, but I think it also goes everywhere, such as office, school setting and not limited only to healthcare settings. 

The most important rule for me is “Be yourself.” It may not sound specific to nursing, but it's important. Being yourself as a nurse means embracing your unique qualities and using them to provide compassionate and effective care to those you serve. 

Here are my “Be yourself ” rules : When talking to patients, be genuine and use your own natural communication style. Avoid using medical jargon excessively if it doesn't feel like you. Express empathy in a manner that feels authentic to you. Whether it's listening to patients, or offering a compassionate smile to them, just find ways to connect that align with your personality. Do the best job that you can—all the time—and not just when people are watching. Treat your patients like you would want to be treated. “Be yourself” is my golden rule when I become a nurse.
