This job is exciting at first and it is a lot of fun, but after a little wile the excitement and the nerves will wear off. You will no longer be nervous on the BS Palliative care calls and the Drama Alerts.
You will never forget the face of the Wife of the first person who you work on who dies.
As you mature you will move from the excitement to the reward of a ROSC or the smile on the face of a husband who's wife fell down and all you did was come and help his wife into her chair with a smile.
Through the bad management, BS calls, pissy drunks, angry pts, and all the other bad that prevails in this business this is the second greatest job in the world (firefighting is the greatest).
And if you are cut out for it, and you do have to be cut out for it, you will not regret your career path.
