This is from my angel wife Sharon, who happens to be a Registered Nurse: 
Somebody asked: “You’re a nurse?!? That’s cool. I wanted to do that when I was a kid. How much do you make?” The nurse replied : “ How much do I make? I can make holding your hand seem like the most important thing in the world when you’re scared. I can make your child breathe when they stop…I can help your father survive a heart attack. I can make myself get up at 5am to make sure your mother has the medicine she needs to live. I work all day to save the lives of strangers. I make my family wait for dinner until I know your family member is taken care of. I skip lunch so that I can make sure that everything I did for your wife today is charted. I work weekends and holidays because people don’t get sick Monday thru Friday. Today I might save your life. How much do I make? All I know is… I make a difference.
