While browsing old papers, I found this note about learning CW – origin unknown.

20 WPM CW.

“It´s tough you say?  Maybe so.   It´s not supposed to be all that easy.  Look at it another way.  Twenty words a minute is only one word every three seconds.

You gonna let a little thing like that stop you?

One word every three seconds!

Most year-old babies talk faster than that.”
