What was the name of your first pet? Where did you put your house keys? How do you get to work every morning? Most likely, you didn't need to look up the answers to these questions. You remembered them. Memory is, without a doubt, the most powerful (and practical) tool of everyday life. By linking both your past and your future, memory gives you the power to plan, to reason, to perceive, and to understand. As long as thinking and insight are important in how we live our lives, memory will be critical as well. And the better your memory, the more information you'll have at your immediate disposal and the better your thinking will be.
