Because we know our minds have the ability to remember I see it as important for a person to ensure that what they do in the present is something they will be proud of and want to remember in the future.
Memories can be very positive of course, however they can also take one's mind and emotions to a dark place better forgotten...But we can't really forget can we? That's why there is such a thing as regret.
It's best to chase one's best life in the present to avoid regret in the future.
Thank you for your post. I hope you have a great weekend.
