How do kids actually stay motivated while learning typing?

We’re building TypeLab, an online typing course for children and teens, and one thing we keep seeing is that motivation drops quickly once the novelty wears off.

From your experience as a parent, teacher, or learner: what actually helps kids stay engaged long enough to build real typing skills? Is it games, visible progress, short sessions, external rewards, or something else entirely?

We’re especially interested in what didn’t work, and why. Honest experiences and examples are very welcome.
