PewDiePie mentioned The Affirmation of Life by Friedrich Nietzsche 1 times

I actually wanted to make this video because I think you will really like Nietzsche as well. He's a german philosopher born in 1844 and before we dig too much into this I just want to preface by saying that you know I'm not an expert I'm just making this video to hopefully inspire you guys to dig into his readings as well because there's so many misconceptions about Nietzsche that sort of makes you wonder if anyone's ever actually read him? As someone who did read him and didn't understand anything but for me it was really fun to discover just how wrong I was. [...] What Nietzsche actually stood for was something really beautiful and that I think a lot of these teenagers could benefit from which is his life affirming philosophy.[...] Nietzsche wants you to recognize life and all its suffering and at the end of it say yes that was life, one more time please once more and that's life affirmation and that's to me it's the beauty of Nietzsche.
