I have to agree with you. I currently work for a private provider and a city service. I really enjoy the private service I work for (granted they aren't like any other I've heard of). My point is that as a new "ROOKIE" to EMS, you will want to try something many people forget to do.
You have two ears/eyes, one mouth...God made you that way for a reason. Shut up, listen and watch everything, and open your mouth when you have a question. Questions are good, even the "stupid" ones. They might be stupid to someone who has been doing this for a while, but to you they are a blessing because no one wants to make a mistake.
Watch out who you apply for, just because someone has cool toys and rigs doesn't mean they have the best ability to meet their payroll.
Most important, have fun and enjoy helping other people! Some of the best friends I have are the result of working in EMS.
