My favourite quote, is one made by the philosopher and writer Anais Nin...
"LIFE EXPANDS AND CONTRACTS WITH YOUR COURAGE"
Courage can be many things. It isn't just to do with brave or dangerous acts. Sometimes courage is to sit and do nothing, to be patient.
Sometimes courage is to listen to a differnent point of view and to even change your stance.
Courage can also be to dare stand up for your rights or values regardless of the consequences.
Courage can be to stick to a resolution.
Courage is being able to make wise choices (see Wisdom 12/12/12)
Courage I believe, overall is to live your AUTHENTIC LIFE whatever that means to you. If you do not do this you feel DIMINISHED...your life will CONTRACT.
I frequently remind myself of this piece of wisdom and try to let it guide my choices.
Hope it is also useful to you.
