Try living like a good person who is happy with whatever life brings their way. Someone who is content with doing what is right now and has a good heart for the future. See how that feels. You have tried the other way of living. Now test this one. Stop troubling yourself from now on. Make your life simple.
Try also how a good man's life; (of one, who is well pleased with those things whatsoever, which among the common changes and chances of this world fall to his own lot and share; and can live well contented and fully satisfied in the justice of his own proper present action, and in the goodness of his disposition for the future:) will agree with thee. Thou hast had experience of that other kind of life: make now trial of this also. Trouble not thyself any more henceforth, reduce thyself unto perfect simplicity.
