“If you have correctly identified what really matters, if you invest your time and energy in it, then it is difficult to regret the choices you make. You become proud of the life you have chosen to live. Will you choose to live a life of purpose and meaning, or will you look back on your one single life with twinges of regret? If you take one thing away from this book, I hope you will remember this: whatever decision or challenge or crossroads you face in your life, simply ask yourself, ‘What is essential?’ Eliminate everything else.”
