Some life, and that to learn a
Some people think that a child only has room for one language in their life, and that to learn a second one, they would find it confusing. This is not true and in fact some places, such as Switzerland, have students learn up to two additional languages and by the time they graduate high school many of them are even trilingual.
You may feel that learning a language now will be too hard, or hardly worth the effort. But you don’t have to be fluent to experience brain benefits, personal satisfaction, or cultural enrichment. Even minimal knowledge of a foreign language can help keep your mind sharper no matter your age.
