I agree with you on that, and it does bother me for sure. At the school where I teach, I always dress sharp and professional. I iron all my shirts and pants b/c not doing so just looks like total sh*t. Some teachers show up looking like a wrinkle-bomb blew up in their room every morning, or show up wearing something that's just not professional.
My parents and grandparents always stressed the importance of looking good, and then the Marine Corps just solidified that for me.
Weird thing that I do...I count the numbers in words and then try to arrange the words into groups with equal letters. The words can be from a conversation I'm having, or a billboards, sign, song, etc. It started long, long ago, and I don't do it much anymore; but every once in a while it creeps back into my head!
