As the owner of two health-care educational institutions, I often come in contact with anxiety-filled faces of individuals who really would like to become health-care professionals but do not know which careers to choose. I have seen many cases of individuals switching from one course to another and later settling for the third course where they think they have found their niche. In one case I had a student who wanted to draw blood but fainted during the introductory video on phlebotomy. I advised her to change her course. This book has been written as informational material for individuals choosing to start with the entry-level health-care courses.
