In response to clients asking for a recommended reading list, I could give a long list but the following are the ones which I think make a magnificent 7:
F**k It by John C Parkin
The Road Less Travelled by M Scott Peck
The 7 habits of highly effective people – Stephen Covey
The Four Agreements by Miguel Luiz
The Obstacle is the way by Ryan holiday
The Power of Now by Eckhart Tolle
The Power of Fun by Catherine Price
