Why my English hasn't improved?
The reason is simple. It's because I didn't study English. I thought my English skill especially speaking could be improved constantly without any effort as I have been staying in Toronto, Canada since 2012. And how about now? Even after 8 years it remains as it is.
And why didn't I study English? It's also easy to answer - because I am lazy...
Better late than never. Let's get started by taking some English courses and studying English with a tutor.
Wish me the best!
