Everyone can master the art of losing; you lose your keys every now and then, you lose a friend occasionally, you lose a lover once or more in a lifetime, you lose a pair of shoes more than once, you lose a parent sometimes and you lose a loved one to death at least once but it's the art of forgetting that no one seems to master;
You can't forget that you lost your keys, you can't forget that you lost your friend, you can never forget that lost lover, you can't forget about your lost pair of shoes, you won't ever forget your lost parent and you most certainly won't forget the loved one you lost to death.

Now if you mastered the art of forgetting, who knows maybe you won't have a frustrated mind and a tired heart.
