Your inner dialogue.

The key to ridding yourself of this attitude of helplessness is to clear your mind of negative inner conversations and replace them with more hopeful messages. You can reframe your perspective by changing and controlling your inner dialogue. The longer negative thoughts are allowed to chun in your mind, the greater the emotional buildup and the potential damage. If you don't recognize and treat it,  you could face the psychological equivalent of pneumonia - depression.
We like to think that our attitudes are affected by what people do and say to us, but in reality, it is what we say to ourselves that has the greatest influence on how we present ourselves to the world.
