Life is meaningless, and the fact that it's meaningless is in of itself meaningless. The endless pursuit to file life meaning is futile. When most people hear that, they find it to be negative, which is what has driven humanity for thousands of years to find the meaning of life. And religion. People can't deal with thinking that they aren't here for some 'purpose'.
Yes, you do have a purpose. Know what that is? Well, if you don't then I sure as hell don't. It's up to you, people. The fact that life is meaningless is a GOOD thing, not a BAD thing. It means it's an empty canvas for you to fill with whatever you want.
So start filling it.
