> Believe me, I've tutored a lot of people, many of which initially disliked math and found it difficult. But after a few tutoring sessions, I could see a little sparkle in their eye that said, "hey, this might be cool".

Exactly the same for me. Honestly, the satisfaction of seeing that "sparkle" in the eye of an initially unmotivated or discouraged student is probably among the most fulfilling moments of my professional career.
