If you could relive the last 10 years with all of the knowledge/wisdom/information of events that you have today, essentially giving you some kind of clairvoyance... What would you do/do differently? I would predict actual future events like who would be president or what diseases or disasters would occur, and then I would make a bunch of bogus predictions to scare the **** out of everyone.
DMT or magic mushroom shall open your third eyes and receive da clairvoyance af. If they cannot open your third eyes then you deserve a shetty or bad trip.
I'd basically ensure I had a really great run in MS / HS and would be really selective about who I met. For kicks I'd pretend to have premonitions of shit that ik will happen regardless but pin it on bad things ppl have done to me or others ik in the past.
I would start working on Artificial Intelligence before any of these corporate cronies, not spend time watching as much anime since I've watched all the latest releases since Winter 2018, learn some other skills/trades since I'd only be eight years of age, and start long-term investing in Amazon/C&P/Intel/StoC/etc..
