Wonderful book
Format: Paperback
This is a great book for those who are interested in looking at the caring side of nursing. We are so caught up in the science, that sometimes people forget that they are taking care of human beings. I would recommend this book to anyone that is a nurse or is thinking about becoming a nurse, and even for any health care practitioner. Jean Watson is amazing, her philosophies can be applied to your every day life. And it also causes the practitioner to focus on their own life, which is very key in being a successful practitioner.

Much Needed Shot of Love for Nurses
Format: Paperback
Although at times this book is a little difficult to read (science and PHD); it is an excellent testimony to our profession as nurses. I've often been asked, "what is is that you do as a nurse?" Through this book, Jean has been able to help me answer this question. She also helped me remember why I became a nurse in the first place-to share a caring moment and touch a life. Thank you, Jean Watson!

A Classic
Format: Paperback
This is my favorite book by Dr. Watson. I have read it many times and continue to learn and deepen my own nursing practice. I highly recommend this book over all others. Whether you've been a nurse for 4 years or 40 years, you'll be surprised at what you'll learn.
