Is it useful or important to "input" without a purpose?
In this sentence, "input" means to read a news-paper and so on.
In Japan, it is said to be important to "input". So many workers read a news-paper on the way to their work and many students are made to read a news-paper, especially column. However, "Japan as No.1" was old and they have not kept it.
Although "input" is important, "thinking as themselves" is thought to be more important.
Why do we input? This is partly because knowledge will be useful in the future. Can we apply everything to "input" ? Its difficult because we forget. For not forgetting, thinking is important and "thinking" means "What's the purpose?"
