The internet has also enriched our lives by providing us with more information than we could ever need, thus making us more independent and effective learners. In the past students had to rely on a teacher or physical books for their education and these were often either unavailable or in a format that most people did not want, but now we can pick and choose what we want to learn. For example, there are now thousands of free online courses available on YouTube that anyone can watch and learn from anywhere in the world.
