> Looking back, I always struggle with writing.

Shouldn't it be "struggled"? (Sorry, I had to.)

"The principle suggests us to focus..." Should not it be: "The principle suggests that we focus..."?

> I can bear the pain of writing in high school, but I almost gave up in university

And this should be "could"?

As a non-native English speaker, your blog post and your interactions and feedback to replies and suggestions to fix some "mistakes" on your blog post is an inspiration for me, because I've always struggled to start writing fearing that I'll make "banal" and "obvious" mistakes that will decrease my credibility on the subject I'm writing about.
