The difference between success and failure is all here, in the details, in the small, boring, repetitive everyday things that nobody wants to do and only you can do. You’re the one who chose to be the entrepreneur and who must lead by example my friend!
I’d ask questions like: What do they do for fun? What drives them? What are they learning? What’s their favorite book? What’s important to them? What makes them tick? What do they teach their kids? Who are their role models? What would they want their tomb stone to say when they die? Etc.
