I agree with the above post. Focusing on school is most important. Take me, I took a year off after high school, I worked a crappy job maybe 3 days week and ate and slept bodybuilding. I took that bodybuilding mentality into school though once I finally went. My main focus now is school no matter what. Bodybuilding will always be there, I'm more concerned about having a REAL job though. I mean sure, we all probably have that dream of competing but seriously, you probably have a better chance of getting into a plane crash...twice.
School makes your life, and though bodybuilding may help it your nothing without school. These days its pretty safe to say you dont get anywhere without school. You going into the medical field is pretty cool man. After I'm done I'm actually thinking about coming back in a few years to get my masters and one day, one day (prays), if I have enough dedication and drive in years, is to go further and possibly break into the medical field myself.
Focus on school man, and good luck.
