When I was in elementary school, I wanted to spell correctly and get 100% on every spelling test. In order to do that, I figured I needed to practice and so when I was speaking, I would spell in my mind every word I spoke out loud . Even today sometimes I subconsciously start spelling things I say. I would also pronounce the words in my mind the way that they were spelled (ex. beautiful I would say in my mind, "bee- aaa- ooo-tee-ful").
My question I've been asking myself is should a misspelled word preclude someone from having a certain job? I would understand if that person were applying for an editor position, but otherwise does spelling have any bearing on how well a person does a job that has nothing to do with spelling?
