What are the answers?

I have some questions I want to ask you. If you were in a room with everyone you ever met, who would be the one you'd look for? If someone gave you a box of everything you have ever lost, what is the first thing you would look for? If you had the chance to relive one day of your life, which day would it be and why? If you could receive a letter from your future self, what advice or insight would you hope to find in it? Imagine you have a chance to revisit a moment from your past. Which moment would you choose and what would you do differently, if anything? If you had to define your purpose in one sentence, what would it be and how does it influence the choices you make in your daily life?
