5. How to Remember What You Read

I believe that if you want to get ahead in life and work, you need to read great books. But I also believe that it’s just as important to remember and recall what we read.

6. How to Read More Books

There’s a lot of advice online on how to read more. But most articles, in my experience, ignore busy professionals trying to balance life and work.

Fortunately, there’s a way to read better books (even if you’re strapped for time like most people).

To learn how to read more, read my article, “How to Read More: A Busy Person’s Guide.”

Or, if you prefer to learn on the go, read my Audible review: “I Tried Audible for 30-Days. Here’s What Happened.”
