When I was a younger, I took New Year resolutions very seriously. One year it was, 'learn French' (never happened) and another year it was, 'change your body'- something which at my age, I am still learning how to do. I never look back which explains why there are literally years in which I have little memory of anything (like between 21 and 30?).

But really, all you need to remember about the past are the things you shouldn't be doing ever again. Always look ahead because that's the only direction you're headed.
