Ed Sim adds color to a good post by Andy Sacks of Judy’s Book about questions you should ask of your business.

I think this highlights a broader and more important entrepreneurial concept–turning your brain back on.

Becoming an entrepreneur requires you to turn your brain back on after quit possibly years of corporate brain drain. You have to open your eyes and see and understand everything that is going on around you. I equate it to the lessons I teach my son about Chess:

• Control the center
• Watch the whole board
• Don’t take everything the competitor gives you
• Have a plan A, have a plan B, have a plan C, assume you are going to play plan B or C
• Wreck the competitors plans’, never follow their plan
