Practicing a foreign language

It's important to practice a foreign language through travelling or even by using the Internet. However, I think that people are busy so they cannot chat every day.

Note:  In written English, it is usually not good to start a sentence with "but," however, it is perfectly fine in spoken English.  Internet is always capitalize.  The word cannot is one word, but usually you will see "can't" more, but it is perfectly fine to use cannot.
