My boss is really quite good at making me feel incompetent.  He leaves me feeling as if he doesn't quite trust me to do things right, even though I haven't made any devastating mistakes in the past four months.  Yesterday I actually found something I do quite well--laying out VCT flooring.  I spent several hours working out the flooring designs for the children's museum, in the art area, the program room, the party room, and three bathrooms.  My boss looked at them and said, "I like this!" which would have been a compliment, had not his voiced dripped with incredulousness.
