You think you have seen it all. New things - they are either too small for you or you have done it. What's left for you are your memories. Then suddenly you catch a breeze. Your sails are full of wind. You are making a 180 degrees turn and moving to a new direction. You are creating new things, but you use your previous experience as a frame. That takes your game to a new level. The new burst of creativity makes new memories and builds new experiences to draw from and to remember later.
