Look your fears in the face and laugh at them.  In this way you take away their power.  In truth, they have no power, only that which
you have given them.  Upon realizing
this, you can take them away in an instant and laugh, not really at your fears,
but at yourself for ever having been afraid or doubting.  Such characteristics are very human, and so
it is understandable that you would doubt and fear.  Rise above the role you play and step into
your full magnificence as a spirit-being-playing-human and you will see why you
do the things you do.  When you can laugh
at yourself (with a dose of compassion, we might add), you will have succeeded in
setting your fears aside once again. 
Once again?  Yes, they come and go
as you continue growing, but far less often.
