The best thing you can do is keep your mouth filled with praise all day long.
Let my mouth be filled with thy praise and with thy honour all the day. - Psalm 71:8
“The greatest saint in the world is not he who prays most or fasts most; it is not he who gives alms, or is most eminent for temperance, chastity or justice. It is he who is most thankful to God.” — William Law
