on on side, you should know that generally people gruntled or upset with something will review it or vent about it. So most people who post a small line or post about hating it usually have their own faults for it, or got a raw deal. Look at most of the best colleges in the USA, most of the reviews posted about them are negative because people want to "teach the evil force a lesson". Take people at my school, plenty of people failed this semester and say the courses are too hard and grading is unfair, but if thats the case then why has about 85% of the class passed each year for the past 60 years... Im not saying everyone who fails is their fault, but many of the people who fail and understand why they failed or admit there was stuff they could have done to not have failed, and those people are less likely to post negative comments.
On the otherside, its not for everyone. Some people get into the clinicals and find that they hate it. Others do it because they hear its a good paying job, or the shortage and feel as though they can get jobs easily. Not many people realize nursing isn't just another job, it has people that rely on you, and facts that you must know. I knew students who were discussing how they couldnt wait to start nursing school and then 4 weeks in at the first clinical they realize they didnt like it, and it wasnt for them. I would suggest you get your foot wet, maybe volunteer or get a job that you can do that is similar. Shadowing can only get you so far, and depending who you shadow can determine a lot (a happy nurse versus a faded nurse, nurse in ER verse nurse in LTC facility).
