A book I have been absolutely loving and have talked about in my classes - Tools of the Titans by Tim Ferris.
Don't let the giant nature of this book scare you! It is a book you can "browse and land" (I just made that up) wherever your curiosity pulls you. To me, it is somewhat of a "toolbox" for habits, rituals and ideas to live an amazing life, extracted from the lives of leaders, interesting people and successful human beings. Tim says, “I created this book, my ultimate notebook of high-leverage tools, for myself. It’s changed my life, and I hope the same for you.”
One of my 9 million favorite parts of the book is page 471 in an interview with Kevin Kelly and he says... "Sit, Sit. Walk, Walk. Don't Wobble". An expression capturing the commitment to be fully in the moment you are in. It's worth a read.
