I am always weary of a teacher that speaks in absolutes. Always do it this way, there is no other way, this is the best way, etc. There is more than one way to get the job done. I like to try new ways to get it done. But don't verbally slap my hand when I don't agree with what is said. I take classes to learn new techniques. I will try them and keep using them only if they make sense to me.
