This is why negative thinking is so addictive.  If you keep holding negative thoughts, you condition your mind to expect and even crave those continued inputs.  Your neurons will even learn to predict the reoccurrence of negative stimuli.  You’ll practically become a negativity magnet.

Consequently, the solution I like best is to stop fighting and surrender.  Instead of resisting the negativity head-on, acknowledge and accept its presence.  This will actually have the effect of raising your consciousness.

Conscious creation

Negativity needn’t be a permanent condition.  You still have the freedom to choose otherwise.  In practice this realization normally happens in layers of unfolding awareness.  You begin to accept and embrace more and more responsibility for your life.
