Why Does Not Ichiro Focus on the Rate of Hits but the Number?

The answer is that Ichiro thinks it is the most important thing to keep his motivation, and so Ichiro focuses on the number of his hit. If he focused on the hitting rate, he knows he can't keep his motivation as long as possible.
It is also the most important thing to find something to keep my motivation on my job as long as possible.
