Perhaps asking key questions will help me learn more about what I know than what I don't know about myself, and also make bets with myself, haha. Following the previous question.
 

For example, in this game where we have to discover a secret character the we can see but we can ask questions. A good starting point would be to ask if it's male or female, which would practically eliminate half the uncertainty. And I bet in this question. 
 

But, where do they use that idea for self-discovery? I mean, could I use something similar to discover my own secret characters in my head?

If I can, what would be the best questions to ask to assess my expectations and eliminate bullshit?
