There is a big difference between this and that.
Request 1: Expand to 3 titled paragraphs: This is a form of cheating yourself
Request 2: Correct grammatic and mispell errors in this paragraph (you write your craft)
In form 1: You are cheating yourself.
In form 2: It helps to have a paragraph grammar mistake free and without mispell errors or sentences that aren't understandable.
Hope this is clear

Does that improve your craft or is that a form of cheating yourself?
