Let’s call them school A and school B.

School A thinks:
Business is an intellectual contest
Opportunities are in the market and our job is to discover them
Exhaustive analysis is the key to success
Risk of failure is bad and should be minimized
Projects should be approved based on their forecast ROI

School B thinks:
Business is a pragmatic discipline
Opportunities are created through what and who we know
Real-world experimentation and iteration are the key to success
The odds of failure don’t matter as much as the potential payoff for succeeding
Projects should be trialed based on affordable loss

I’ve yet to meet a successful entrepreneur who didn’t subscribe to school B, and I’ve yet to meet any school A types who have created a game-changing new product or service.

Different beliefs, different behaviours, different results.
