This is a very fine post, Yea Wen. As Bernard states, you do a great job moving from the general to specific. You illustrate a bit of your character and your skills needs clearly and with concrete examples. Thanks for that!
There are a few minor language issues:
1) Communications skills are not like any other subject which I can spend time looking through textbooks and then excel in it. >>>
Communications skills are not like any other subject FOR which I can spend time looking through textbooks and then excel in it.
2) It requires a lot of practice and also the correct skills. >>> It? The subject? Or communication skills?
3) I will like to make use ... >>> I want to make use / I would like to ....
4) I feel that this is somewhat true of our society, including myself ... >>> I feel that this is somewhat true of many people in our society, including myself ....
I look forward to reading more of your writing!
I think the structure of your blog is OK. You went from a general concept of communication to your personal view of the course.
One thing that you might not be aware is that sometimes your sentences becomes too long and it starts to get hard to read. Perhaps you can consider breaking down long sentences into smaller parts.
Another issue I find it interesting is the tendency to use the word "also". Each paragraph has an "also" except for the third. Actually you could remove some of those "also" and the meaning of the sentence would still remain the same.
Anyway, I still think you did a good job in writing this blog. Cheers :)
