"Of course it's hard, you haven't done it before!"

Edit: Only really applies to a very specific kind of situation. Doesn't help if the person has already encountered that type of problem, and had their confidence shattered by a bad teacher or a hostile environment. My sister in law is a math lecturer who often does remedial classes, and she spends a lot of her time trying to teach students not to be afraid of the subject matter.
