Question: If you had the confirmation that you were an old soul, what impact would that have on you? What would you do differently? Why would that matter to you? What would you do differently if you knew for sure you aren't an old soul?

With all due respect, that knowledge might be counterproductive to your mission for this incarnation. Maybe, being preoccupied of this question is a good indication that you aren't an old soul. Maybe, unconsciously you're looking for some solid support to give your opinions more weight in your argumentations with others, which would just be frivolous.
