The Power of Pause by Nance Guilmartin is an excellent book. It is basically about how to take a pause so you can think more rationally and strategically and thus give yourself a better chance of success. This ability to pause so you can think before you act is the first step to thinking critically. Nance provides excellent easy to implement exercises to help you master the technique.
This practical method helps even the most overwhelmed among us take a moment to pause and wonder what’s called for when we feel short on time, attention, temper, or choices. In that instant, we can use a simple method to rewire our overloaded circuits, tap into our “missing-in-action” common sense, regain control of our reactions, and raise our communication intelligence. This process is not about slowing down the pace of workday life. It is about enabling anyone to be your best when dealing with deadlines, change, or fast-moving opportunities.
