Edward de Bono on Humour

"Humor is by far the most significant activity of the human brain."
(Edward de Bono)

Not sure that it is the most significant, but it is definitely very important to a healthy outlook on life and of self.

On Fear

"I learned that courage was not the absence of fear, but the triumph over it.  I felt fear myself more times than I can remember, but I hid it behind a mask of boldness.  The brave man is not he who does not feel afraid, but he who conquers that fear."
(Nelson Mandela)

Mindfulness

"Mindfulness is not a modern spiritual movement.  It's simply you at your most natural state of being."
(Brad Waters)

On Courage

"Deep down in the human spirit, there is a reservoir of courage.  It is always available, always waiting to be discovered."
(Pema Chodron)

Chopra on Same Old, Same Old

"Every time you are tempted to react in the same old way, ask if you want to be a prisoner of the past or a pioneer of the future."
(Deepak Chopra)

Good advice.

Deepak Chopra on Stillness

"In the midst of movement and chaos, keep stillness inside of you."
(Deepak Chopra)

Yes.

Unpleasant Memories

"I no longer dodge the memory as if rotting vegetables were flying at my face."
(Sandra Upson)
