You are the actual, factual embodiment of desire fulfilled.

You, as spirit, as soul, desired to be embodied.  You achieved the fulfillment of that desire at your conception.  You succeeded.  You fulfilled your desire.  You accomplished your purpose.

You cannot fail because you already succeeded!

All you have to do now is live your life in a way seems the best to you, in a way that pleases you, in a way that is satisfying.  You already succeeded.  It is done.  Just go on.
