With lots of hard work, motivation and dedication.

Here are Steve’s tips: Learning depends on you, not your teacher or school. Be motivated.  Language learning takes time, so stick with it!  Your attitude is 80% of the battle. Put your emphasis on comprehension. If you can speak but you can’t understand, you don’t know enough.  Do lots of listening and reading.  Transcripts of audio are helpful because there’s less pressure. Don’t be hard on yourself. You’re pushing you’re limits, so it shouldn’t be easy!  But tension and pressure are the enemy of success, so be persistent, not stressed. and I hope you the best and GO AHEAD

I am trying my best to improve my spoken English too. You should find a partner who can help you with your English learning.And he can help you practice your English.

Which aspects do you mean? Listening: maybe you could listen to various English songs and watch different kinds of movies&TV dramas. Writing: practice and hard work, if you don't write then you won't get improved. Speaking: actually, it is also what I am trying to improve, Is anybody else could help~? Reading: try to read more English materials. then you will be used to read it more quickly. It's a long process and don't be too anxious about it. Just keep moving and you will find it much more interesting and fulfilled in the whole learning process.
