"Write What You Think is Not Important", a better Advice?

First time I read this title, I don't believe it.
I think it's impossible to get success in blog if we share something not important to anothers.
But when I read the reason why he wrote this title,
Now I understand.
And now I think it's the fact. I agree with that.
I agree when he gave advice like "don't write what you think your readers want you to write, but write whatever you want to write".
and this one, "If you only write about what you think will makes your readers happy, you will stuck someday".
So, I don't know is this article good for you or not, I just want to write.
But, I wish all readers will be happy for this all.

Enjoy your write.
