Why do you feel dread before doing something?  The immediate answer is because you are inflicting pressure upon yourself to achieve a self-imposed result.  Even if someone other than you is expecting that result, because you have accepted this as necessary, it is indeed self-imposed.  The dread, then, comes from fear, and under it all is your identification with yourself as only human.  At another level, you know you are both human and spirit.  Go to that awareness at the first sign of dread.  Face your fears as the beautiful light you are and watch them dissolve.  The smile that comes from remembering you are spirit and stepping back into that light dissolves self-imposed discomforts.  Smile on.  You are so very loved.
