My experience (and from talking to others) is that it will take you 2 or 3 times as long as you think it will take to succeed after Business School. So take it easy running up your student loans and credit card debts expecting you’re going to be a rock star later.
You were smart enough to get in to Business School. That doesn’t mean you are smarter than other people without an MBA. Stay humble.
In my B-School, there were always amazingly talented executives coming in to give talks on business and life. They’d always compliment us on what a great school we attended and why we had our future by the tail. It made us all feel invincible — destined to succeed once we set out on our various career paths. It doesn’t work that way. I know B-School classmates who’ve failed miserably, under-achieved, gotten divorced, gotten severely depressed, etc. B-School is a great educational opportunity in life, but you still have to go out there and succeed. Nothing is given to you as a birthright.
You’ve probably worked at companies were people who’ve been there for 2 decades roll their eyes telling you about the new hotshot MBA who just started and is now telling everyone how to do their jobs. It’s so clear to him, yet others find it deeply offensive that he would think he knows how the company works when they’ve spent countless years there and are still trying to figure it out. All hotshot MBAs should wear tape over their mouths for the first 3 months on the job and not be allowed to “fix” anything.
In my experience, B-School makes you less creative, the longer you’re in it. They teach courses on entrepreneurship but it’s kind of an oxymoron the idea of the analysis paralyses B-School Students being entrepreneurial. You will learn a lot of tools and frameworks in B-School, but you won’t learn how to start a company. You just need to start a company.
