Help with writing.....?

I have to write a paper on what my perfect world would be like. I think the world would be boring if it was "perfect", and besides everyone has a different version for perfect so you can't have a perfect world in the first place. I decided that I'm going to write about how the world being imperfect is perfect, because it is in it's own way. I just need some more examples on why our world is perfectly imperfect. Anything will help! Thank You!
