I spent most of the last week in a class for my job. It was really a terrific opportunity to learn things applicable to my job and useful for my personal and professional development. Sometime during the week, I remembered a conversation I had with my then-boss when I was a little baby engineer. He said he was going to take an American History course at a local college. When I asked why, expecting him to give me a well-roundedness, or management-degree argument, he said "Because I haven't learned anything in a while."
Hmm. I've been chewing on that in for a dozen years. This was someone who made his living researching and applying new technologies. And he was telling me he hadn't learned anything in a while. In a sense, I guess this was a well-roundedness argument. It also sets the scale for what he considered a "learning".
Lately I've been drawn to topics that require research moreso than I've been in the past. Been putting them off because I "haven't had time" to learn about them. That sets a scale, too, doesn't it?
