In today's lesson I'm going to show you six mistakes that real students of mine have made – and you might be making, too! The purpose of this lesson is not to make you feel bad about those mistakes, but instead to learn from them.

One problem with language learning is that if you make a fairly minor mistake that doesn't affect communication, native speakers often don't correct you because they understood what you meant in general and they don't want to make you feel bad by pointing out an error in your grammar.
And then you might go on making the same mistake for months or even years!
