Performance, feedback, revision

I think that being able to do revisions on certain ideas are important. this makes human able to correct himself from mistakes. mistakes are from wrong decisions and decisions are made through process of thoughts. the process of human thoughts are not computers, we human often make mistakes. for example, the essays we write in class, one often mistakenly write something that means the other unintended, sentence structure, grammar, misspell, or sentences that just doesn't make sense at all.  

in class, we make revisions from our drafts, this is a good way to find out that if there can be a improvement on the paper. through the work done on the paper, the student will be able to revision and learn a better way of writing.
