What to ask a millionaire?

Hi, I have a lunch coming next week with a millionaire (CTO of Fortune 500) . It's a rare chance so I'm making a short list of questions that I'm going to ask him. Please let me know if I miss anything important. Your advice is really appreciated!

Also, I'll be glad to ask him any questions you may have, and post his answers here next week.

1/What are 3 skills you think the most important to your success?

2/ Is networking a must to be successful? If yes, How do you expand your networks? (go to conf, meetup, keep in touch with old friends...)

3/ If one advice you could tell your younger self, what would that be?

4/ Do you read often? How do you apply knowledge in books?

5/ Is being a millionaire what you originally aimed for or it's just a sweet side-effect? :)

6/ Which one is more important to your success? Technical skills or entrepreneurship?
