安河内哲也先生 3 Rules of Learning English by Yasukochi:
1. Make mistakes — don’t think that’s a good advice
2. Be self-confident — self-confidence has very little to do with your ability to speak English — 安河内哲也先生 should know that
Be proud of Japanese English — be proud all you want, just make sure people understand your katakana English
3. Speak in a loud voice — people are who they are, they won’t change just because 安河内哲也先生 tells them to
I believe that Yasukochi 安河内哲也先生 means good, he does care about English education in Japan, his advice is well-intentioned but not very practical.
A much more practical advice is: use monolingual learner’s dictionaries
