My understanding the reason people get college degrees is that it's like an investment: you put time and money in to go to school, then in theory you are able to get a better paying job. I know some people feal that going to school is to learn, but you can learn without paying a ton of money and going to college (and in college I find I mainly teach myself).
I'm finishing my bachelor in computer science. While I've learned some areas I like and dislike, I'm not sure of my career path. How does one decide to go back to school? For example what makes people get their master degree, is it because they want a job that requires it?
I had a theoretical computer science class that I really didn't like and I struggled in. I got a tutor who has her master degree in computer science. She now works at a retail store for sporting goods. Good for her that she works a job she's happy at, but I'm curious how does it happen someone gets a master degree for a job that only requires a high school certificate?
In summary I'm asking:
1) How do you find out which doors are opened by getting a higher or another degree?
2) How do you prevent getting a degree that isn't useful?
*When I say degree, I really mean any certificate like diploma etc.
For example I like working with people so I think I'd enjoy the business side more so I'm thinking of eventually getting my MBA. Is my reasoning valid?
