I've been on this site for almost two years now, and some people from time to time have criticised about the poor healthcare they've received, and how nursing standards in particular have fallen. I personally think that when every single nurse enters their chosen career, they sort of see it as a calling, a vocation and need to want to help others. It's not about the money, it's about caring, and wanting to help.
I've recently come across this little ditto which I think sums it up nicely.
