“Visionaries are specially afraid of a false negative: that customers will reject a flawed MVP that is too small or too limited.

The solution to this dilemma is a commitment to iteration. You have to commit to a locked-in agreement—ahead of time—that no matter what comes of testing the MVP, you will not give up hope. Successful entrepreneurs do not give up at the first sign of trouble, nor do they persevere the plan right into the ground. Instead, they process a unique combination of perseverance and flexibility.

The MVP is just the first step on a journey of learning. Down that road – after many iterations – you may learn that some element of your product or strategy is flawed and decide it is time to make a change, which I call a pivot, to a different method for achieving your vision”
