like when I hear from a patient or their family ...
"Im so glad your my nurse today" or they come up to me in the community and say "We can't thank you enough for compassionate care of our Mother" etc.
Bottom line: Its nice to hear that you truely are making a difference in someone's life.
P.S. A few of my friends and I would listen to the soundtrack from "Rocky Balboa" on the way to school or clinicals and not only was it funny but it was also motivational.. I strongly suggest study groups and keep in mind why you want to be a nurse and what your dream nursing assignment is.
