Expressways of knowledge

Following the previous article, I continue introducing Mr.Habu.
In 2002, he said,
"A big change occurred in the shogi world, because of IT Revolution. A expressway for improving the shogi skill was laid out all at once. But there is a great traffic jam at the end of the expressways."

This remark was introduced by Mochio Umeda and became the topic in Japan. I think that this remark applies to every field. Of course it applies to a field of the investment, too.

I feel that the more I learn, the worse I am stuck in heavy traffic. I am looking for a method to surmount a traffic jam. It may be one choice to get off  the expressway.
