Clueless in life but got into an M7 MBA. Now what?

Hi all,

I graduated with a non-IT engineering degree, 3 years of engineering work.

I was lucky to land a M7 MBA (non-HSW). Now my life is a blank page as I have no idea what I want to do in the future, at least short-term post-MBA.

I'm averagely smart, managed a 760 GMAT. I'm comfortable with numbers and able to hold a conversation (not out of this world good though).

In the future my dream is to run my own business (not necessarily tech startup, as I'd rather sell lemonade as long as it is profitable). I know MBA sounds like the anti-thesis of running a business. But with a non-business background I feel B-school is a good place for me to catch up.

What post-MBA choice will help me reach my goal faster, considering my background? ( PE/HF/VC is out of question, I won't bother) So far I can only think of consulting as an option that prefers my M7 cert while doesn't place a heavy emphasis on my pre-MBA experience.

Should I even think about IBD? Will IBD be better for someone who want to acquire sufficient business knowledge to start a company in the future? Is IBD even feasible for someone who had 0 experience pre-MBA?

I'll appreciate all your inputs. Be it negative or positive. Thank you:)
