If I can't read it, I won't!

[Sarge]

One of my bosses used to insist that I or anyone else read his reports after they were typed. He claimed that when he read them he would see what he had written originally and miss all the errors.

I often have this same problem. It is a trick your mind will play on you. Your mind already knows what you meant to write, so that is what it sees. I have gone back over an essay before and wondered just how I could have missed that, or found whole words missing.
