Humor
Laugh at your mistakes.
Worry never added an hour to anyone's life.

Gratitude

 It is not happiness that comes first

and then we are grateful.

It is when we are grateful that we feel happy. 

From sorrow he turneth to bliss,

from anguish to joy.

His grief and mourning yield to delight and rapture.

Am I Happy?
How often do I laugh?
Do I believe I know what's better for me than God?

When thou strippest the wrappings of illusion

from off thine heart, 

the lights of oneness will be made manifest.
