By far the best book I read this summer was The ONE Thing: The Surprisingly Simple Truth Behind Extraordinary Results by Gary W. Keller and Jay Papasan.
Obviously, this book is about focus. It's about asking a powerful question: What's the ONE Thing you can do such that by doing it everything else will be easier or unnecessary?
You see, I don't have an issue focusing. When I need to finalise a task, I'm pretty good at hammering it.
But I do have an issue with doing too many things and wanting to be part of very many things. It's hard for me to say no when others come to invite me to be a part of their projects which often have very little to do with what my priorities are at the moment. As the authors explain, when you say yes to something you are inevitably saying no to something else (often what matters most to you) in order to find time for the former.
So this book got me thinking a lot about focusing only on the right things at a given time and prioritising my energy for those. It also made me realise that I need to be more vigorous about how and when I should be utilising this energy best. That includes my own time management and planning as well as my surroundings because according to research we lose 28 percent of an average workday to multitasking ineffectiveness and on top of that, we get interrupted every 11 minutes and then spend almost a third of our day recovering from these distractions.
