We all want to live a happy life and have a right to do so, whether through work or spiritual practice. I'm subject to destructive emotions like anger and jealousy the same as you, but we all have potential for good too.

Consequently we lack a clear awareness of the inner values that are the basis of a happy life.
From a Buddhist point of view, the actual experience of death is very important. Although how or where we will be reborn is generally dependent on karmic forces, our state of mind at the time of death can influence the quality of our next rebirth. So at the moment of death, in spite of the great variety of karmas we have accumulated, if we make a special effort to generate a virtuous state of mind, we may strengthen and activate a virtuous karma, and so bring about a happy rebirth.

I believe that to meet the challenge of our times, human beings will have to develop a greater sense of universal responsibility. We must all learn to work not just for our own self, family, or nation but for the benefit of all humankind. Universal responsibility is the key to human survival.
