1) Routine. Getting up at the same time every morning, read a newspaper, make breakfast, etc. I want to go into my MBA running like a well-oiled machine. If I stop working, I’ll just degenerate into never wearing pants at home and playing video games.
2) Money. Unless you are independently wealthy, a month or two of salary helps the financial burden that an MBA carries.
1) Not having enough time to relax. I can see that happening, but then again, my philosophy isn’t about rewarding myself or my family on specific occasions, i.e birthdays. I try to relax on a year-long basis. If you try to fit all your relaxing into a specific period of time, doesn’t that seem kind of stressful in itself?
2) Self reflection. This is the biggest con of not taking a break until your MBA begins. The MBA is a journey on self-reflection and you should probably figure out who you are and what you want to do, generally speaking, before you start your MBA program. There are just too many opportunities that you need to filter without getting swamped.
