You know that i have joined my current job one year ago, and i have learned english for 13 years. Yestoday, we(wiht my colleagues) met with our customer, from Alstom company, i did not know what his name is. We talked about the nuclear power generator. In fact, i listened, and they talked. I was shamed that i just sliped out one word: different, after i figered here and there.
I do not know the reason and i admit that i was lack of courage. Maybe i have no idea, maybe i can not express myself clearly, but i am pressed by the strange people or things, on the other word, i have a bad psychological state, and it has last for many years.
Now, i want to change, change my habitual idea, change my style, change my way of thinking, and then change my life. Unluckily, i do not not how to do, and what is you advice, my dear friend.
