I'm currently re-reading the humbly titled "The Greatness Guide: Powerful Secrets for Getting to World Class" by Robin Sharma. It's a nice easy read at Christmas time because each chapter is only a couple of pages long, so I can pick it up and put it down in between peeling the sprouts and fixing the Christmas tree lights (again).
It's an easy read, but that doesn't mean it's light on content. Sharma manages to offer 101 focused nuggets of advice for one's approach to life (professional and personal). Whilst the book can be summarised as yet another publication encouraging positive mental attitude and a can-do approach, Sharma's real-life illustrations manage to lift the book above several others that I've begun reading (but not finished).
