Has anyone found that their class notes might not be adequate ?

Or does anyone find it difficult to re-read their notes or written articles/paper because when he/she starts re-reading or revising it, he/she might be gripped by anxious thoughts of ,"Hey, I have so much to revise and revise it with absolute understanding".

It's as if the brain has some sorta OCD that revisions has to be done with certain steps and when the brain gets overwhelmed with high standards of revisions, it quits.

Let me know if anyone finds it difficult to revise or re-read anything..
Thanks.
