Starting today,I will make time to write articles in English to learn English.
Sometimes,though,I think I could use the help of a translation site,My goal is to eventually be able to write in English on my own.
Best regards.

Today's theme is [Meaning of Seriousness].
Seriousness means a person's own life.In other words,If I want my life to be great,I must have my own seriousness.

So what kind of behavior the term "seriousness" refer to in the first place?
I think It's 'do all I can.

In other words,I look up everything I don't know, devote all my spare time to it, and think about it all the time.
I believe this is what real "seriousness" is all about.

Do not pretend to be serious. It can be said that not pretending is seriousness.
