No attitude...if you decide to use your cert and you don't actually have a sincere motivation to do that work, then problems come up.
Ask any seasoned EMS professional to pick out the premeds in a crowd of EMTs. They can do it fairly easily. Im not making a sweeping generalization that ALL premeds who become EMTs for medical school are not sincere, but it is true that many arent.
You are working with people's lives. You are in charge of their safety for 10-30 minutes. Things you do (or dont do) have the potential to seriously harm a person. If you are on a truck because you want to be able to put it on a paper application, then theres reason for me to believe that your head isnt in the game 100% of the time.
EMT work IS NOT being a doctor. Much of the time you are helping an elderly person get up or calming someone who really doesnt have anything wrong with them. For someone who has some incorrect idealistic vision of medicine, this can be a bore and therefore they will slack off with their duties. However, its when you slack off and lose focus that the old woman who says she fell this morning and feels weak now *raps out in front of you while doing a routine transport. Then, when you are supposed to remember your proper CPR technique and how to handle these situations, you freeze because you didn't take your EMT education seriously because you figured as soon as you got it, it can go on your application.
Does this happen. Yes, Ive witnessed it. This person was later fired for inability to handle the job appropriately. Does it happen to everyone....no, and I didnt say it did. Im just saying, consider what the job is before you enter it. Have respect for the field and the people you come across in it. Dont do it for the application only. I promise you that this will be noted and you will not be well received by your crew or your co-workers who do have a passion for it.
Also, like I said, your time won't be pleasant because in many (NOT ALL) states, EMT courses cost money. Unless you pick up the cost yourself, or do it through school, some agency will probably be paying to train you. If you don't use this certification, that agency just wasted money on you and your training. This is not a good thing.
Call me what you what, but Ive had quite a few experiences in my 7 years on that warrant my comments. When you experience some of the same things about EMS and EMT training, then come back and have an appropriate, well informed conversation with me
