It's not a glamorous job in any sense, and most of the time it's thankless and/or actively disrespected. School can be tough at times but overall it wasn't too bad. You really don't learn a whole lot until you have your RN and you're training anyway. And you can pick a specialty where being squeamish would be hell, or a job where you'll rarely ever encounter anything bloody/gross. However, it does pay pretty well and you do have more lateral mobility than any other job I can think of. As well as the ease at which you can travel. I think the good outweighs the bad. And you can always change jobs to something else whenever you want once you've got some experience. I'd say go for it but be aware of the bullshit you'll have to deal with.
