I recommend 5 questions at the max. Make 2-3 of those open-ended. You learn so much more when people explain their answers instead of just selecting “Yes,” “No,” or “C.” Also, that way you can capture the person’s words and feelings. Here are some questions that gave me amazing insights that’ll work for you: What do you want for yourself [in specific topic]? What are you doing now? How does that make you feel?
