@ERDoc:
1. Listen to those who have been doing this longer, unless they say, "We've always done it this way so why should we change it."
2. Eyes and ears open at all times, this is how you will learn the practice of pre-hospital medicine and asses/treat your pt.
3. You don't need to carry 1000 things on your belt or in your cargo pants. You will find that the more a person carries, the less experienced they are.
4. When someone tells you they feel like they are going to die, be scared, because they are usually correct.
5. It's not your emergency, don't panic and your heart rate shouldn't be higher than the pt's heart rate (with a few obvious exceptions)
6. A screaming kid is a breathing kid
7. No matter how many times someone says it, seconds rarely matter, minutes might but that case is rare.
8. Light and sirens are useless most of the time
9. All bleeding stops eventually
10. Many things that are done in the field are not necessary and will be discontinued in the ER. Don't criticize the ER for doing things differently that what your protocols say.
11. Helicopters are cool but are not needed as much as they are used
12. Have fun doing the job, otherwise you will burn out quickly
13. Never be afraid to ask for help. This is both on a call when you are not sure what to do or after a call when the demons start showing up.

@EpiEMS :
On operational (non-clinical matters);
1) Prepare for internal volunteer politics. Heck, be prepared, if you're in a combined career/volunteer agency, for "them versus us" situations.
2) Be nice to everyone. Everyone.
3) Be prepared for yelling. People love to yell, especially those who are useless.
4) Skip the bat belt. You (may) need shears, you need a penlight or flashlight, you need (or can borrow) a stethoscope, and you need two pairs of gloves, but you don't need a window punch, hemostats, or bandage scissors.
5) Have fun
6) Ask for help when you need it.
7) Don't endanger (or overexert) yourself. Call PD. Call FD. Call whomever you need.
On the clinical side:
1) Always wear gloves. Even better, always wear gloves and eye protection.
2) Have fun.
3) Ask for help when you need it.
4) If you have a question about a decision a higher cert provider makes that is not immediately dangerous to the patient, ask after the call. However, if you think they're doing something that you think is contraindicated, and you can back it up, say it. Say it so they hear you.
5) If you are on an ALS/BLS truck or have an ALS fly car, and the medic turfs the call to you, but you're not comfortable, DO NOT accept the patient as your responsibility.
6) Get comfy with carrying bags and moving stretchers - you're BLS, so you'll be doing that a lot.
7)
Sick kids look sick, as ERDoc said.
8) Lights and sirens are generally dumb (as ERDoc said).
9) Most calls will be stupid - this is just the fact.
10) If the patient is really sick, you'll probably be able to tell.
11) Call medical control if you have to. High risk refusal? Call 'em.
12) Call ALS whenever indicated. High risk refusal? Let ALS decide, if you have the opportunity.
Neither one of these are mine, i copied and pasted.
