This question really comes down to a matter of opinion so it differs from person to person. I can see it both ways. Personally, I believe being a firefighter is no small thing. If this is something you chose to pursue then I admire you. You will be in a position to help people in their biggest time of need. As someone else already mentioned, that is a very satisfying and gratifying career.
However, that being said, it is not for everyone. You have to have the stomach to see some of the world's most gruesome things. Think major injures and burned bodies. On top of that, the hours are not ideal, you are always at risk, and you want to consider your mental health depending on what you see on the job.
But on the negative side you are away from your family for 24 hours at a time, there are fires at all hours and all weather, and you are risking your life to save others. You have to weight that in as well.
Being a Firefighter is a distinguished career goal. Having a career as a public servant is both satisfying and gratifying. It's a career that has great benefits and working with the public helping when people need help is extremely satisfying. I think you will do well with being a firefighter.
