Deviating from all the business related books, one needs to also focus on personal development and fulfilment in order to perform at one’s best.
A book that I’ve found quite informative and beneficial is The Power of Now.
In the first chapter, Tolle introduces readers to enlightenment and its natural enemy, the mind. He awakens readers to their role as a creator of pain and shows them how to have a pain-free identity by living fully in the present. The journey is thrilling, and along the way, the author shows how to connect to the indestructible essence of our Being, "the eternal, ever-present One Life beyond the myriad forms of life that are subject to birth and death."
The book shows that only after regaining awareness of Being, liberated from Mind and intensely in the Now, is there Enlightenment.
