7. Is business school necessary for entrepreneurs?

For an entrepreneur, there are high opportunity costs to spend two years in academia vs. actually building a business. However, academia is an environment where great innovation and minds come together, and as we have seen, it’s the “breeding ground” for many of the most important technology businesses in the world.

8. What was the last book you read?

The Visual Display of Quantitative Information [by Edward Tufte].

9. What has been your biggest failure?

Failures are learning lessons that I tuck away and move on from quickly. Generally, failures often stem from not taking risks or not learning quickly enough.

10. What was the most important thing you learned in school?

History does indeed repeat itself — this applies to business and technology as it is a key method to predict the future.
