If you stay with your past regret, you’ll break through. You’ll realize that every moment spent in remorse is another regretful moment for eternity. You’ll finally understand, in your bones, the truth of Nietzsche’s wise advice: “Never yield to remorse, but at once tell yourself: remorse would simply mean adding to the first act of stupidity a second.”~ Kyle Eschenroeder from, https://www.artofmanliness.com/2018/01/01/eternal-return-ultimate-new-years-resolution/
We don’t literally live this exact same life over and over, as encapsulated by the idea of “Eternal Return”.
But it IS an interesting thought experiment. It is exceedingly difficult to break outside of my own self-perspective — arguably, it impossible to break out since what perspective do I have, other than MY own. But trying to think of things from new perspectives . . . it’s like trying to catch a glimpse of the back of my own head in a fun-house of mirrors.
