My Confidence Is Back

Today I met my ex-PM under my office building. I was not excited and forgot what I felt yesterday. I could understand what he said to me. I don't know what happen to my English skill because it seems to fluctuate all the time. Sometimes I can understand what a foreigner says to me but sometimes I can't understand at all.

Someone Punches on My Face

Today I feel like someone punches me on my face. I didn't understand what my ex-PM said to me. That let me know my English is not good enough for working or living or studying in English country.

That's true I hardly speak English in my workplace. Indeed, I hardly use English in my workplace. Even I think I practice English every day, but that is not enough to improve my English. I still can't use English like I use Thai.
Sometimes I need to narrate my story to foreigners with colorful words but eventually it can't be as I thought. I fail.

What I should do to improve my English in a short period. I need to be ready before the examination comes. Do I attempt enough? Do I study hard enough? Or I still let time pass me by. Or it is just to waste my time.
