As I have been working on a book myself on scheduling and organization, I have reviewed a large number of books on these topics. One of them is Lighten Up, Love What You Have, Have What You Need, Be Happier with Less by Peter Walsh. Walsh is a clutter expert and organizational expert who has written many books on the subject.
Here is one interpretation of takeaway points from his book.
In this book, the author focuses a lot on adjusting priorities and self assessment to come to grips with what is really important. As the title advises: Love What You Have, Have What You Need, Be Happier with Less.
Hope you find this helpful, as I did. I'm about to do another cleanout of my stuff.
Trust Me, I'm a Doctor.
