If you have built castles in the air, your work need not be lost; that is where they should be. Now put the foundations under them. 1(p303)-Henry David Thoreau, 1854 The expressions are not novel or infrequent. Most assuredly, we've all heard them: quite regularly, in fact. Occasionally, we hear it from our offspring and from our children's classmates at graduation parties and other casual social events. We even hear it from our colleagues' children when they swing by the office or clinic, and often, we hear it from many of our patients during the course of our work days. Athletic training educators frequently hear it from teenage students shopping for colleges and speaking of potential career choices while sitting in our offices or touring our campus facilities. And yes, quite commonly, and perhaps even increasingly, we hear it from our own athletic training majors during advising sessions or candid conversations about their future plans: ''I am going to medical school.'' ''After I finish my athletic training degree, I am going to physical therapy school.'' ''I'm taking the necessary prerequisites so that I can go to physician assistant school.'' ''I am going to nursing school so that I can become a nurse.''
