> A life well-lived is really what we should all hope for.
That doesn't make sense. A life however-lived implies you're dead. You cannot admire your well-lived life.
> I can’t change the past, but I can change the future.

Maybe you're not a native speaker. The reason why I reply is because I notice that many people fall into language traps when reasoning about something philosophical. The result of that reasoning looks good but doesn't check out and hence doesn't get you anywhere in terms of actually realizing something important.
