Mark Forster's new book, "Do it Tomorrow", is quite likely the only book you'll ever need to manage your time and your life (I should know--I've read most of the others!)
From closed lists to the manana principle, Mark's thinking is infused with clarity, applicability and a deep knowledge of human nature gleaned from his years of hands-on experience in coaching. You will find truly new ideas here--ideas that may go against your deeply held beliefs about time management (what? DON'T prioritise??); but start applying them and you'll see startling results almost immediately.
I've been applying Mark's principles for a month now and I can't imagine working any other way. I'm now on top of my work, have systems in place for incoming jobs, and I have time for my personal life. Every item on my "will-do" list gets crossed out by the end of the day. All with zero stress.
Most of all, the principles are simple and easy to apply on a daily basis, unlike so many books out there that necessitate you to spend more time planning what to do than actually doing it--so easy to apply, in fact, that you can start implementing them even before you finish reading the book!
