Something, then rest
The secret is to not allow the fact that you can't do everything keep you from doing something. Something, then rest. Something, then rest.
...So we saunter toward the Holy Land, till one day the sun shall shine more brightly than ever... shall perchance shine into our minds and hearts, and light up our whole lives with a great awakening light, as warm and serene and golden as on a bank-side in autumn.
