Viktor Frankl was a holocaust survivor who studied how people were able to survive in horrific conditions. I read his book, Man's Search for Meaning, in High School and found it very helpful.

I also touch on Camus' books: The Plague and The Myth of Sisyphus in this video.

I mention my video on perceptualism. If you're interested, here's the link. https://facingup.club/perceptualism/
