Dear Mr. Emperor,
Thank you so much for coming yesterday.
I was greatly influenced by your talk. Especially, the part that you have a strong heart to keep learning English, and always have goals at all time made me rethink my own process of learning. I easily give up my attempt, but now I'm convinced that I have to kick out that bad "habit".
Finally, I thought that it is very important to have competitive English skills. So, I will work harder with my fellow students from now on.
