Olfactory fallacy and assessment of the academic cage

It's wonderful how addictive it is to just write what it is I feel like writing without having to type a perfectly punctuated reference, worry about my syntax or even logical fallacies. For example:
You may be, aware that the majority of people have a sense of smell. Therefore smelling is good.

But it still feels slightly wrong to write words that aren't highly structured or referencing anything in particular.
I still feel like it will be assessed at some point. And that disturbs me, because I would like to feel free to write my ideas without apprehension.
