Start with Death, End with Life
The top regret of the dying is to not having the courage to live a life true to themselves.
Where do you find that courage?
You start by accepting one day you will die.
But don't end there. That will only give stress and worry. Instead, move on to having compassion for yourself.
That compassion for yourself will lead you to learn not to care what people think and to follow your heart's true desire.
And that will cause you to finally live the life you want to live.
