Marketing Major

As a senior in high school planning to major in business/marketing I have a few questions that I would appreciate being answered by the experienced.

1. How is the average work day? (pressure, deadlines, stress)

2. How difficult is it being a business marketing major in college? (workload, time)

3. Satisfaction level of your job or for college students, major?

4. What degree you have earned, the position you are now and how long of experience you needed to earn that position, and if possible, the average salary earned each year.

Thanks!
