Over time, Zeke also began making better choices about what work to take on. So long as he arrived at work already feeling tired, he instinctively put his energy into executing simple tasks. Doing so allowed him to feel productive without having to expend too much energy. It was the equivalent, he came to recognize, of a sugar high. It was satisfying to accomplish a series of relatively simple tasks, but the pleasure didn’t last for long.
I love the idea of tackling some simple tasks to build yourself up, if you're lacking energy one morning. While this states to tackle important things first—because tackling small tasks creates a "sugar high that burns out just as fast"—I think for myself, I could see myself getting confident with seeing my small To Do list dwindle, and then give me the high and energy to then jump to other big projects (that maybe I was too exhausted to start on a particularly hard morning). On the other hand, I can also see myself just wanting to stick to easy tasks all day and avoiding the big To Do's then. This would be worth experimenting with because everyone works in different ways!
