It's been my observation that students stall out on things like "varying sentence structure" or polishing every word in the Intro paragraph when they don't have anything to say.
I'm never sure which comes first --
> Are they dithering around with trivia because they have nothing to say?
> Or is this hypnotic fixation on trivia blocking their output?
This is a difficult topic. When I tried to think of 5 paragraphs' topic sentences on the theme: My Aspirations -- I got nothing.
I wonder if you should change your theme. If I were writing your paper, I would have a LOT to say on the topic: "Why I Am an Atheist"
- First realization: Age 6 -- Santa Claus is a fake:
1) That's when I learned that it profits me to greet every absurd assertion with skepticism
2) That's when I realized that when people tell you all about an invisible magic being, they are messing with you
- Search for verification or falsification of my atheism
1) Nothing I ever read supported the idea
2) In fact, the opposite: The more I read, the sillier it all became
3) Comparative religious study taught me that one fairy tale for grown-ups has no more to support it than any other fairy tale for grown-ups
4) Or any other fairy tale for children, if it comes to that
- Disproving the existence of God
1) It can be shown that God cannot exist in principle
2) It can be shown that God does not exist in fact
- Value of atheism
1) Intellectual honesty
2) Intellectual rigor
3) Freedom from oppression
and so on.
I have a feeling atheists have a LOT to say.
Once you have a lot to say, the mechanics are just mechanics. The problems with writing a long paper mostly solve themselves, and those that don't are easily fixed with common sense work.
Best wishes in your studies
