It is difficult to learn a new language

There are many difficulties to learn a new language.
First of all, We hardly use it in daily life. So, we don't realize the need for new language and neglect learning.
Next, we are ashamed of using new language. Because we have a dread of mistake, we hesitate speaking new language.
Finally, we don't know foreign culture. They say that language express culture. But, we almost have no opportunity to experience foreign culture a lifetime.
If you want to learn a new language, you should pay attention to these reasons.
