Negativity is a poison that kills dreams and cripples one's potential. It leads to depression, physical illness, and the destruction of possibilities. Repeatedly exposing one's mind to negative thoughts has detrimental effects, though the negativity cannot be seen. To eliminate this poison, one must monitor one's thoughts and words, eliminating complaints and excuses, instead adopting a vocabulary of success using passionate, positive speech and expressions of enthusiasm. Shifting one's thinking from negative to positive involves focusing on gratitude for life's gifts and finding the good in every situation.
