Found this wonderful old column of her’s from RetroRenovation of all places:

JUST FOR TODAY – I will live through the next 12 hours and not try to tackle all life’s problems at once
JUST FOR TODAY – I will improve my mind. I will learn something useful. I will read something that requires effort, thought and concentration
JUST FOR TODAY – I will be agreeable. I will look my best, speak in a well-modulated voice, be courteous and considerate.
JUST FOR TODAY – I will not find fault with friend, relative or colleague. I will not try to change or improve anyone but myself.
JUST FOR TODAY – I will have a program. I might not follow it exactly but I will have it. I will save myself from two enemies – hurry and indecision.
JUST FOR TODAY – I will exercise my character in three ways. I will do a good turn and keep it a secret. If anyone finds out it won’t count.
JUST FOR TODAY – I will do two things I don’t want to do, just for the exercise.
JUST FOR TODAY – I will be unafraid. Especially will I be unafraid to enjoy what is beautiful and believe that as I give to the world, the world will give to me.

Postscript – Amy is absolutely correct from what I see. How odd the original column was run without attributing it correctly.
