I am a businessman running a small computer company where I am facing a high workload and a lot of stress. I found this book a few years ago.
It gives a very thorough guide to how to get your life in the direction that you wish, while - what's really important - maintaining a balanced life. If you are a person with high ambitions, but feel that you do not have the time necessary to accomplish your goals, this book suggests a very simple daily checklist you can use to maintain the balance. It encourages you to develop clarity in what's important, to make a habit out of improving your habits, and suggests how you can develop your own inspiring guidelines. After reading the book, I have worked a lot to adapt the excellent ideas to my own life, and it has really been worth the effort!
