It makes absolutely no difference if you think about it. It's not like choices are made for you even if the universe is determindric.
If the world is or isn't deterministic it's not like anything would meaningfully be different - things would still be unpredictable to us. In an indeterministic universe randomness would play a part in outcomes, but that's worthless to us. This meme is about choices anyways, randomness or determinism doesn't matter in the end.
Taking ALL of the paths was never really an option though. Celebrate all the new paths that opened because of the one you chose instead of dwelling on the ones you didn't.
That just makes me think of Everything Everywhere All At Once. I recommend watching it to anyone who feels they wasted their past options. Or if you like kick-ass martial arts shit, haha
I've accepted my past mistakes and, for the most part, don't get get bothered by them anymore. However, what does bother me is really not having an identity and passion to know where I want to take my life. It feels like I'm just living day to day until I eventually become dust.
Maybe start meditating. I know this is like, stupid random advice thrown at you from who knows where on the Internet, but it is definitely a journey worth starting.
Imagine some sort of a polynomial function f(x) = r * x * (1-x) that is also depending on some constant r in range 0 < r < 1.
You apply x = f(x) for many times, at your wish. Think of it as a for-loop, or f(f(f(...f(f(x))...))). The resulting value will reside (converge) to some value.
So, this looped function sets to some stable point with any r in range until x < 3. After that, it doesn't converge but it will constantly jump between one of 2 points, then 4, 8, ... and at some point it goes wacky-macky.
The graph from Wikipedia merely shows the probability of the value f(f(f(...f(f(x))...))) for all r in the given range.
