Why do we need a goal? The answer to this question touches on the deepest, most basic need in humans: purpose. It is the why, the drive, and the reason for doing what you do. The purpose of having a goal is that it gives you a reason to keep playing the game of life. When you get down to the basics, it gives your life meaning. It is necessary if you want to keep moving forward. If you're not moving forward, you might as well pack it in and accept mediocrity.
