You are left with your obsessions, your quirks, and all the personality traits that either you inherited from your genetic entity, or were somehow imprinted upon you in your formative years.
You interpret the world through this instrument. So your flaws, and your features help construct your perception of the world. So what you see and think about the world is also what you see and think about yourself.
If you judge the world harshly, you are also judging yourself harshly. If you give the world "a break" you are giving yourself a break.
If you think the world is just a rollicking carnival you are that carnival too. If you think it's a bleak and forbidding place, you are a bleak and forbidding place too.
I vote for the carnival. It's got it's fun side of light and thunder, and cheap thrills and cotton candy, and got it's dark side too, of the false show, the con, and the coldness behind the curtain.
