Don't try to do all these things at once. Don't try to do two things at a time. Don't try to do two things at once. Don't try to do two things at the same time. Don't try to duck out early. Where's your sense of responsibility? Don't try to find fault with others. Don't try to keep her to yourself. Don't try to lift anything heavy for a while. Don't try to lift something too heavy for you. Don't try to memorize what you are going to say. Doing so will make your testimony sound “pat” and unconvincing. Don't try too hard. Don't try to pass the buck.
