We create lists to help us remember what we want to achieve in a day, but using them effectively is an entirely different matter. Often, we push the biggest or most important tasks to the top, and let the little things flounder. The Zeigarnik Effect states that people are hardwired to remember uncompleted or interrupted tasks better than completed tasks. Essentially, the items you push to the bottom of your to-do list are the ones that take up the most brain space. No matter how small, forgotten tasks can cloud your mind, so try to confront seemingly insignificant tasks first. With each item you tick off, you should find your mental clarity returning, and be in a better position to sink your teeth into bigger projects.
