As a fairly new Episcopalian (since getting sober) I am partial to their "For Today" prayer, which in part reads:
O God:
Give me strength to live another day;
Let me not turn coward before its difficulties or prove recreant to its duties;
Let me not lose faith in other people;
Keep me sweet and sound of heart, in spite of ingratitude, treachery, or meanness;
Preserve me from minding little stings or giving them;
Help me to keep my heart clean, and to live so honestly and fearlessly that no outward failure can dishearten me or take away the joy of conscious integrity;
