We are mortal, that's just a fact of life. I do agree with the comment OP though that both: - Maximising every day is bad - Ignoring life is bad

In the end its all about balance and content as the top voted comment goes.

I would still recommend the book to everyone!

EDIT: Also as one of the comments notes here:

"If you don't feel some existential dread at some point it's because you aren't being honest with yourself"
