I'm learning Greek and have started commenting an Instagram account for Greek learners.  I find that often learners are too shy to comment on things...

Vacation ;)

Usually you can't 'turn a window' as they are set in place. Perhaps you mean to 'pull down the shade' or 'close the curtains'? Can you please shut the curtains? The sun is shining right in my eyes. Can you please lower the shade? The sun is shining right in my eyes.

Communication Skills

I was working for two big companies as an executive secretary which is an important role in the company.  It is similar to how a flight attendant represents their airline. Because People(clients or passengers) know the company through our service and communication skills, that means we have a good chance to make a great first impression between the company and people.

During my work experience, I communicated with many people every day and tried to help them the best I could. I believe being a good listener is one of the best ways to be a good communicator and it does always works! I would love to be a part of the best airline in the world using the efficient coordinating experiences from my past with my open-minded personality.

Because you started with "I was working for" I assume that you no longer work for those companies-- that is why I changed it all to past tense ;)  

About the new Star Wars

Yesterday I watched the new Star Wars movie. I would like to give my review about it. But at first I need to tell you something about the meaning of this series for me. The first three movies are without a doubt the best for me. It was so great watching it in my childhood, I have so many nostalgic memories and I'm not against watching them again. There was a comfortable atmosphere in these movies despite the lack of action. Now everything is has changed (is different) and we have the antithesis. Yesterday I saw a lot of action- it was  very good and high quality action, but it was too much for me. I can't say that I didn't like the movie, but it could be a more calm and sensitive movie.

My job

I’m very lucky because I usually walk go to work walking every day because my office is five minutes away from my house. I start work at ten and I finish at two. I have to check my e-mail, write some letters, revise the bank account or and make some phone calls. I often go to the café at midday to drink some herbal tea or some coffee. At the beginning of the month I have a lot of work to do.

Sounds nice!  Many people would love to be able to walk to work in just 5 minutes :)  

It is time to improve my vocabulary comprehension

Last night I watched a video talks about the English learning English. In this video, it says that input is very important. For English learning, you need to grasp enough vocabulary before you start to speak out a in complete sentences. If you can pronounce the IPA sounds correctly and know grammar rules exactly, you are still limited to in expressing yourself effectively. So vocabulary is the bar of your English expressions.
In this video, it says 30,000 vocabulary words is are needed if you want to read novels and understand 98% of the related contents.
Now I can understand my teachers even when they speak fast, also they can understand me in lessons. So I think it is time to improve my vocabulary.

I 100% agree with you!  I think that VOCABULARY should be the #1 priority for students.  I also believe that confidence is very important as well-so keep practicing and building up your comfort level with English!
