When I was younger, I always thought the purpose of life was to enjoy it. Looking back on it, I still see no problem with that statement, people overthink simple things, amirite?
I know this sounds a lot like John Lennon's quote/story, but I swear it is 100% true, I didn't even know who The Beatles were at that age. Of course, people may go ahead and comment "no, they meant, you know, why are we here?" and other similar statements, but to be honest, I think that's stupid. It won't do us much good endlessly speculating why we're here on earth, so why not just be a good person to others and enjoy the ride? I'm not bashing any religions, by the way.
