@happy1 "There are many ways to do this such as – talk to professors in the field, talk to people currently working in the field, talk to career services and understand what job opportunities are available, try to get an internship in the area, shadow professionals, take an introductory class in the discipline etc. "
The best advise out of that group is to talk to someone in the field while considering a major. Nothing else and nobody else is going to tell you the full story. Certainly nobody at my school did. The teacher who was also my coworker asked if I wanted to make a career out of hotels right after I graduated. When I said I was going to look into other fields, he said, “Yeah. Why would you waste the time?” He knew full well that the amount of time it takes to get promoted to a decent position was simply not worth it.
