How do I save the world?

I feel like my ultimate mission in life is to save the world. I'm trying hard to liberate my own heart from the psychological shackles placed upon me by the material realm and I feel so powerless.

I look towards Jung, gnosticism, mysticism, Christ, socialism, anarchism, environmentalism and all the other isms and know the symptoms and disease of the world yet I feel still bound by the shackles of it all and feel powerless to enact change. I want to help people but I feel I can't because I'm so bound in bed and don't know how to move
