You should tell yourself frequently 'I will only react to constructive suggestions.' This gives you positive ammunition against your own negative thoughts and those of others.
Jane RobertsAs you sow in your subconscious mind, so shall you reap in your body and environment. Whatever your conscious mind assumes and believes to be true, your subconscious mind will accept and bring to pass. Whatever you habitually think sinks into the subconscious. The subconscious is the seat of the emotions and is a creative mind. Once subconscious accepts an idea, it begins to execute it. Whatever you feel is true, your subconscious will accept and bring forth into experience.
