What Lurkily said. Tghey do have trouble staying on task. One of my viallgers dislikes work, and he is adept at almost everything, but i usually find him somewhere else than where i want him to be.

I had this girl who didn't like wood, she ran away from the huts, until I forced her to.

Well, my suggestion is to just stay with the villager. If you stick by them and help them to learn, you will be surprised what they can achieve in the end
