You can't. Not unless you knock out teeth which may cause teeth to move to fill the gaps (much like extracting teeth before braces to allow them to straighten). Just work with what you've got.
I've got crooked teeth and had braces to straighten them. I gave up wearing my retainer so my teeth have moved slightly and are now slightly crooked again - it makes teeth cleaning difficult as my front teeth overlap slightly. I know people with really crooked teeth and so much food gets trapped where the teeth overlap...so be thankful you can have a nice clean mouth!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
