We forget things we try to remember. We remember things we'd rather forget. The most frightening thing about memory is that it leaves no choice. It has mastered an incomprehensible art of forgetting. It erases, it smudges, it fills in blank spaces with details that don't exist. But however we remember it––or choose to remember it––the past is the foundation that holds our lives in place. Without its support, we'd have nothing for guidance. We spend so much time focused on what lies ahead, when what has fallen behind is just as important. What defines us isn't where we're going, but where we've been. Although there are places and people we will never see again, and although we move on and let them go, they remain a part of who we are.

We deliberately forget because forgetting is a blessing. On both an emotional level and a spiritual level, forgetting is a natural part of the human experience and a natural function of the human brain. It is a feature, not a bug, one that saves us from being owned by our memories. Can a world that never forgets be a world that truly forgives?
 

      ― Tim Challies, The Next Story: Life and Faith After the Digital Explosion

There is no man, however wise, who has not at some period of his youth said things, or lived in a way the consciousness of which is so unpleasant to him in later life that he would gladly, if he could, expunge it from his memory.
 

                 - Marcel Proust

Your memory is a monster; you forget - it doesn't. It simply files things away. It keeps things for you, or hides things from you - and summons them to your recall with a will of its own. You think you have a memory; but it has you!
 

                          -John Irving

It's like forgetting the words to your favorite song. You can believe it, you were always singing along. It was so easy and the words so sweet. You can't remember, you try to feel the beat.
