EMS is a job of extremes, you will:
1. work with some of the hardest working people that you will ever meet, or someone who brings a new level of lazy.
2. work with someone that you enjoy, or someone that can't stand to be around for another minute.
3. work with someone that cares about being professional around a patient, or someone who keeps getting called into the office to explain their actions.
4. someone who cares about their personal appearance, and the way their rig looks, or someone that looks the same as the homeless person you just brought in.
5. someone who is willing to keep learning, or someone who already knows everything.
Finally before you know it, you yourself, start falling into these categories. Personally I love this job, I can't picture doing anything else, but there are times you just shake your head and wonder WTF.
