I mean what happens to us may just happen, and maybe what happens has nothing to do with us and our world.
Then again, maybe experience is all we have and all we are, and adds up to what we call "world."
So then we have our insecurities, and then we surmise that the world is some elaborate Rube-Goldberg-like-construction of insecurities (our's and other's) piled on top of each other.
And maybe you can't really run from, or deny, your insecurities. And maybe your insecurities are insecurities for a good reason.
So really then you must find some sort of security in your castle of insecurities...
And that's what we call a "happy existence!"
