Continue having the same passion, spirit and motivation

Do you know Yoshiharu Habu ?

He is one of the best Shogi(Japanese chess) players in Japan. The book which described him as "In human history, the person who thought most deeply" was published recently in Japan. I respect him very much, too.

In his book which became the best seller in Japan several years ago, there are such words;
"Talent is to continue having the same passion, spirit and motivation."

In the stock market, all people try hard to achieve profit. Even if we make an effort, we may be not adequately rewarded. In such situation, it is important whether we can continue passion. If we continue without quitting, at least, we will be able to profit from the person who gave it up.

It seems to apply to our life, not only to investment.
