Oooh, I actually took a non credit course in college almost 19 years ago on the 7 habits...

And recently a former partner sent me photos of some books that used to be mine. And The Power of Focus was one of them. I now remember it did indeed have a really big impact on me at the time. Read it probably 15-17 years ago. A repeat is in store here, or at least of a summarized version in my Headspace app.
