You'll get this inspirational rush of how amazing everything is, how vast the universe, how incredibly unusual for life to exist and for us specifically as a species to exist. And the advanced state we're in, able to do almost anything.
And then you realize that you're using this incredible and very temporary opportunity to sit in a chair for most of your waking hours, for decades in a row.
You're not exploring anything, you're not celebrating life, not producing any meaning. You just sit there, like a robot, pissing it all away. Not depressing enough? Your existence is actually the top 10% of humanity.
Anyway, have a great day.
