Live your life. :)
Memories in principle are some of the most important moments in our lives bottled and up and served to our minds on occasion. Never be a stooge and try to make your future as similar to your past as possible to try and match the memories of old. Alternatively, take time each day to make yourself better in one way or another, drawing from your past experiences and memories, in an effort to make the best future for yourself as possible.
Also, be sure to live in each moment, because the important moments we live today can only be experienced in a physical manner once. Though there will be memories later, shoot for not having any memories that are full of regret.
Remember that though the past will never completely die, you can still make big changes in your lifes by jumping big hurdles, and conquering the huge challenges we are able to be faced with.
Never take a moment for granted, and try to see the value in every moment
