Some years ago I tried to give advice to a friend's cousin when she was starting her own business. She pretty much told me "I have an MBA from a prestigious business school so thanks but no thanks". 6 months later she had burned through a fairly substantial bank loan. Her business had failed and she took a marketing manager job at a big company, meanwhile my business was better than ever reaching 1M in annual revenue for the first time.
There is a lesson there.
