You speak of doing good to the world. Is the world such a small thing? And who are you, pray, to do good to the world? First realise God, see Him by means of spiritual discipline. If He imparts power you can do good to others; otherwise not.
We should reflect on the idea that since the beginning of time sentient beings have been mentally unstable because they have been slaves of delusion, they lack the eye of wisdom to see the path leading to nirvana and enlightenment, and they lack the necessary guidance of a spiritual teacher.

Real art, like the wife of an affectionate husband, needs no ornaments. But counterfeit art, like a prostitute, must always be decked out. The cause of production of real art is the artist's inner need to express a feeling that has accumulated...The cause of counterfeit art, as of prostitution, is gain. The consequence of true art is the introduction of a new feeling into the intercourse of life... The consequences of counterfeit art are the perversion of man, pleasure which never satisfies, and the weakening of man's spiritual strength.
