Reading is “input”, and I think I should also make “output.”
The output means “writing books.”
There are about 30 authors of my favorite, whose books I certainly buy and read.
Some of them write more than ten books a year.
If one of my favorite authors doesn’t write any books more than one year, I wonder, “Is there anything wrong with him, or is he becoming an idle man?”
I wrote a book last year.
If I don’t want to be an idle man, I have to write a book also this year.
