When I was teaching at the junior high level, I had my students keep a quote notebook. Every day, their first order of business was to enter the day's quotation written on the chalkboard. They followed a very simple template. Date, quote, author. As an example, let me give one of my favorites that I often assigned.
January 7, 1980
"Work spares us from three great evils: boredom, vice, and need."
At the end of the year, every student compiled somewhere between 160 and 180 quotes. (For various reasons, some schooldays might not have one.)
Like any good teacher, I practiced what I preached. I kept my own personal quote notebook. And still do. Whenever I come across a sentence or passage in whatever I'm reading that's too good to forget, it goes down in my commonplace book. That's what it was called in the distant past when many writers kept track of their favorite lines.
Here's a quote from my Commonplace Book . Excuse the caps, but it is a particular commonplace book after all. The following entry may also introduce you to the Japanese language. And if you memorize the Japanese as I have, you might even say you know a little Japanese. True, very little. And in a very limited sense . But still true.
Furu ike ya;
Mizu no oto.
Translation: The ancient pond here. / A frog jumps into the pond:/ Sound of the water.
Soon you may be fluent in some Japanese. Especially when the subject of frogs comes up.
