No. How do you think your students would feel if they knew this is how you think of them? I know lots of insecure people, some who are new but still learning, some very skilled in some areas with holes in others but their skills areas way more then make up for their deficiencies, some who just have anxiety issues who don't have any skill issues at all. And a few who really might be in over their heads. The last category is the smallest.
I'm very direct and honest with them about things just like this. I don't hold punches. I teach them to work the problem [1] instead of whining or wasting time on spinning their mental tires.
