My first day on italki

It is my first day on italki. I am excited about it. I think it is very difficult to improve my English skill. But there is no easy thing in the world, especially to learning something. I hope I can do it better someday. Good luck to me! Wish me luck!

{"Wish me luck!" is a typical English expression; it means that you asking others to wish you good luck. If you say "good luck to me" it sounds like you are wishing yourself good luck...}

Good luck!
