Apologies in advance for the existential crises that I may very well spark with this post.
I think I'm on like my fifth or sixth quarter-life crisis, so... yeah.
If you're someone who gets freaked out by existential 'what am I doing with my life?' stuff, consider this your warning!
I've never really wondered about what my life's purpose is - my life's purpose is books.
I've never doubted that I'm on this planet to read and write.
I don't doubt it any more than we doubt as a species that we're on this planet to breathe, eat, and sleep.
