How many times you would hear "no" and keep believing you are right?

Howard Schultz, CEO Starbucks asked more than 242 people to invest in Starbucks in 1987. Buy out price from owners was 3.8 mln $. He saw opportunity. He talked to more than 242 people to get financing. And literally 242 people said "no". He kept working. He was moving forward hearing "no" 242 times.

At the deadline Bill Gates Senior saved the deal in 1987. One meeting changed everything. The rest is history we see today. How many of potential investors are you willing to met? How many times you would hear "no" and keep believing you are right?
