Learning English

I come back to Japan and my room. I'm going to practice dance in my room.

One of my Japanese colleagues at workplace in Taiwan can not read and speak English, but his annual income is above 10 million yen. He is a very skilful person at his work. A Japanese can work and earn money abroad without English if he/she is skilful.

The foreword of Longman dictionary as below is not true for Japanese at present.

"Young people the world over know that English is the most important single tool they need to achieve success in their careers."

I believe that English brings me freedom. The freedom may have no value for my colleague above. It's precious for me, though.
