I think a certain amount of inner peace is instilled in the person with no regrets.
Should death come calling this very instant, they would comply calmly.
Because they lived life to the full and that means there would be no unease in calling it quits here.
I think this level of serenity is achievable by all and your journey can start by answering this question:
If you were to pop your clogs right here and now, what regrets or unfinished business would pain you?
