Working with children makes you happy. When you teach them and they make a progress in their development, this let you be proud of them.
Using my language skills, I could go with children for a study visit in some english- speaking countries. So they would understand the importance of learning English and another languages.
More than that, there are a lot of abilities to tell children about different counties. So then you could make an interesting quiz about everything they know.
Looking how “your” kids grew up and succeed in studying foreign languages let you think, that their life would be great.
