Is man a lost cause?

Hi everyone,
The last two weeks, I have been thinking questions, what is wrong with man? What is wrong with the human race? Why do we keeping fighting? why do we hate each other so much? We cannot exist without each other, I see the human race as whole body with all its moving parts and organs, nerves everything. We co-existing and helping each other to progress to a higher self of realization. But some how a disease has taken over the body and contaminate its wonderful working parts. Causing all types of problems across the world. I believe the problem has manifested in mans thoughts and words and deeds. This problem is ancient and over done. I believe hatred and indifference has become a part of mans consciousness, that he does not know how to control it.

I feel at a loss most of the time. Because of the way we treat each other. The pain that exist in peoples hearts and minds is almost overwhelming. I still believe their are people in the world who are content, and being happy with who they are. I feel like I live in world of darkness, and great deal of sadness. I look very hard for a sign of light and joy, and peace. I look within myself I see it and feel it. I make great efforts to make others see the light and feel it. There are days it does not work. I wonder why people aren't living their dreams and enjoying life to the fullest? I wonder why we keep creating the same picture in our consciousness and playing the same scene in this world. Why we try to prevent the common man from living their dream, I see if people are living their dreams we wouldn't have time to create wars, or try to take over another country. We would be too busy creating what makes us happy and fulfilled. Working as a whole unit of peace, love and joy. What makes you happy? What gives you fulfillment? What gives you joy? You can realize yourself being in peace, joy, harmony, and happiness.

You may think I am crazy,or I dreaming. But i think that all of us should start looking within ourselves and look for what is causing our unhappiness our discontent.
