The events that raise our life expectation bars way too high

Sometimes the events in the past have raised our life expectation bars way too high that everything else after is just a blur shadow of that...no matter how hard we try afterwards all our effort is also just a slight shadow of the past...how to get the satisfaction of the felt memories, how achieve or over achieve what has already raised the highest bars?? Can the past ghosts lead you to the achievable success or will the memories`s shadow not ever let you enjoy today...
