1. Not too late...But it's "go time" as far as making a decision
2. Don't have to be "mr./mrs. wonderful" as far as personality to match ED - course it always helps
3. Accents welcome
4. Multi-tasking is EXTREMELY important in EM
5. There is some level of emotional baggage in all fields of medicine - you're caring for people not upholstering furniture
6. Per your multiple-choice "pressure" situation - Radiology, FM, Surgery, etc. (i.e., ALL fields) are under varying levels of rather IMMENSE pressure. For instance, in real world Radiology, you have to crank through a LOT of images and there is always a time-crunch along with pressure of possibly missing something. FM has huge time-crunch pressure when they're running 3-5 rooms at once trying to make ends meet and cranking through 15 minute visits that turn into 45 minute visits as their waiting room continues to back up.....
Food for thought.
