I'm with Sofficat. When I first opened this thread, I figured it was about waiting to hear whether we were in or not. Let todays troubles be enough for today. Worrying about something years away will just make it difficult to handle the day to day stress. I don't know what you life is like right now, so I won't give the 'just enjoy life' advice. What I will say is that you know it is important to do as well as possible, given your life circumstances, in school and to gain veterinary experience in a variety of areas. Focus on those priorities and on figuring out who you are (and by that, I don't mean pre-vet, student, etc....I mean all the components in that.) Explore as much as you can, so that you don't have doubts later on about the path you are chosing. If you feel that you must do something more right now, improve your study skills, look for opportunities to work with vets in less common areas (wildlife rehab, zoo, farm) and in specialities (behavior, rehabilitation.) Working with vets that tend to working dogs can be a very different experience, because the priorities are very different. The other thing that you can do now is keep an eye on the issues in veterinary medicine from various perspectives.
Good luck!
