The flip side is that many business programs will not accept students without work experience. You're likely to find that most schools actually suggest whetting your whistle in the workplace for at least a year prior to returning for an advanced degree. Talk to admissions advisors and see what each school requires and suggests. And know what to expect. After busting your hump for four years as an undergrad, you're now about to find yourself taking on an even bigger challenge.
Teachers demand a lot of work from their grad students.
If you can't deliver, don't expect to stay around too long. Your graduate schedule will be packed with class time, meetings, and study sessions. I'd scarf down lunch in 10 minutes and begin a deep dive into my reading and homework. The next day, I'd get up and do it all over again. Advanced education must be weighed against the real world experience you might gain during the same amount of time.
