“Take any decision you want to make and plot it on such an axis. I have been trying to lose weight unsuccessfully for the past several years. Now I have decided to give it another shot. There are four possible ways (see Figure 3.1). Stopping carbs is a sure shot way, but it is hard. Cutting fats is an equally hard way, but my dietician friend tells me I will eat more carbs and cutting fats will actually make no difference. Walking for 30 minutes a day is easy, but unlikely to make a difference. So I have decided to cut breakfast. Looking at results and my mood at 12 noon though, I might have to opt for the fourth quadrant.”
