Why are you here?
It’s one of the core questions of human existence, really, because without any purpose there’s no reason to live. Some people would frame this question as, “Why are WE here?”, but that’s really only motivating to philosophers. It really hits home when you make it personal.
By default, I suppose, I’m here because of the random circumstances of my birth and upbringing. But that only says how I ended up acting the way I do, not that there’s a reason for me to be here in the first place.
