Memories....
Capture the memories of the past so that you can appreciate where you are coming from in the future.
Memory is a wonderful thing if you don't have to deal with past.
Life is short, time is fast, no replay, no rewind, so enjoy every moment as it comes and cherish every memory made because they always come in handy when life deals you some heavy blow.
You flashback to the memories and remember which course you are on and why you are on that path.
