Questions about my possible profession

I'd want to know how much money I would make. Knowing if I will be able to support my kids and my family, and know if I will be able to put food on the table. I'd also want to know the work conditions. Is it a short tempered workplace? Or is it rather calm? Is it enjoyable? I want to know about things concerning my overall growth in that field, and if it's a job I will want to have ten years from my start of working there. Are there many benefits? Will I get good health care or that terrible kind that makes you pay more than half? Is it stressful? If so, is it worth the stress to work there anyway? Why is it worth it? Is management considerably smart or considerably stupid? Is it possible to get this job with just a bachelor's degree in my field? Or should I pursue more college classes after four years? Overall, I believe that these are some of the more important questions to ask going into my field.
