Shaking away Negativity

I quote from Terry Orlick:

Negativity sucks away energy. If part of the negativity stems from your attitude or perspective, commit yourself at the beginning of each day and each activity to find something positive in yourself and in others around you. If the people around you are negative and you can't change that, either remove yourself from the situation or view it simply as one obstacle you face in pursuing your own potential. Stay focused on your own goals and make the best of the situation.
