When you do anything in life, you must have some sort of motivation in order to keep things moving forward. Have you ever thought about what motivates you to study English?
We teach one group of highly motivated students, year after year. Why are they motivated? Because they all go overseas for extended periods. It's like all or nothing with such a group. Most of these guys and gals give their 100% each and every class. They also do a lot of preparation and self-study to ensure they will be successful.
From a teaching perspective, this is a dream group to teach. They approach everything with a clear focus and an end goal in their sights. This is how ALL students should approach learning a language or anything, really.
What is holding you back?
You must find your motivation. Don't be lazy!
