It's hard to be the guy who wants to help everyone learn in class.
Let me try that again...
It's hard to be the guy who wants to help everyone learn in and out of class, especially when the teacher cracks jokes about you, and people don't show an extended interest in learning beyond class.
If you're in this for a career, you should be like a sponge. You should want to know EVERYTHING about everything you come across. Knowing "the minimum" isn't enough to get by. That's like taking the FR or EMR class, and not doing any A&P & Patho studying outside of class.
With resources like http://www.theeemtspot.com , http://paramedicine101.blogspot.com , and the various podcasts; MedicCast , EMS Garage , EMSLive , you should spend a certain time per week brushing up on your knowledge, or learning something new.
Medicine is always changing & expanding. Stay ahead of the game.
You should be eating/sleeping/breathing this stuff, so you can be the best possible advocate for your patient.
