I would want to tell my past self that I’m trans and they should take HRT ASAP and that all my friends and family are accepting and that I don’t need to wait until I’m 30 to come out.
Ask my future self. Telling my past self something is very likely to have no affect on my life (what if past actions only affect that “me” and not me-me), whereas asking my future self something will always end up with me gaining information - no guarantee its relevant, but it’s more likely to be.
“Tell me the most important thing you can tell me”
My future self will know best about what I need to know. Winning lottery/investments can make me rich now, but maybe there’s a nuclear war, climate apocalypse, or some other disaster in 5 years and my future self can tell me where to be and what to do before it starts.
I would probably go for the generic “buy as much bitcoin as you can, dump it all at 55k in March 2021 and put it all on Nvidia and sell it may 2024”.
Boring advice, but can’t think of anything that would have a greater impact.
Eh, Nvidia is up more than 1200% since then. You’d be a billionaire at that point, interest rates wouldn’t matter to you.
Realistically I’m sure I’d end up using it for financial gain either way.
Future Self: What’s the next Nvidia stock?
Past self has more monkey paw possibilities, but I think I’d go with something like, “Buy all the surplus compute you can to generate bitcoin in 2009 and hold it until $64,000.”
That’s too much work. Just buy $1000 worth of bitcoin in 2010 and sell it all at 50k, which means you can cash it in 2 years earlier and still make WAY more than you’ll ever be able to spend.
At that point you will be affecting the entire market though. So things might become unpredictable.
You can ask your future self stuff right now. You won’t get the answer until you answer it in the future, but the question is possible.
All answers are from the future, just like all photographs are of the past
