The best thing to do is to speak to nurses themselves, preferably peers. I suggest your peers if you have any, because most of our friends share some core values; this is why we associate with each other.
I do have a passion for nursing, but, I do not appreciate the backbiting behaviors that are so dominant in my profession. The difference, to me, between nursing and other jobs is that we are more dependent on each other, due to different levels of experience, education and talents, and we need all of this to save a life. I am a new nurse, but not new to nursing itself. I am trying to find the place where most of my talents can be displayed, in the safest environment possible. I know this will take time.
Basically, most people here are frustrated because we do have a passion for nursing and wish to see positive patient outcomes. The problem is other nurses, physicians and unempathetic managers that throw crap in our paths and rain on our parades.
Also, reading here helps, especially once you get into the foxholes with us. But, there are also positives. They may be far and few for most of us, but, they are the glue that get us to keep trying. Good luck!
