Giving up attachment to the world does not mean that you set yourself apart from it. Generating a desire for others to be happy increases your humanity. As you become less attached to the world, you become more humane. As the very purpose of spiritual practice is to help others, you must remain in society.
I am sure I have heard this several times from places I can't recall, but it's not already in the Gaia Quotes database, so I add this profound insight from the fields of psychological healing and spiritual evolution. It sure has helped me.
Only when the mind is tranquil-through self-knowledge and not through imposed self-discipline-only then, in that tranquillity, in that silence, can reality come into being. It is only then that there can be bliss, that there can be creative action.
God does not give heed to the ambitiousness of our prayers, because he is always ready to give to us his light, not a visible light but an intellectual and spiritual one; but we are not always ready to receive it when we turn aside and down to other things out of a desire for temporal things.
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.
The dangers is that every religion, including the Catholic one, says "I have the ultimate truth." Then you start to rely on the priest, the mullah, the rabbi, or whoever, to be responsible for your acts. In fact, you are the only one who is responsible.
We may now have reached a point where this gap in our make-up has become unsustainable; partly because what in the past would have counted as material plenty has become the norm for the majority in much of the world; and partly because the slow retreat of religion that coincided with the spread of a capitalist economy has left a gaping hole in millions of people's lives.

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. However, our existing education system is oriented towards material development; neglecting inner values. Consequently we lack a clear awareness of the inner values that are the basis of a happy life.
Water is fluid, soft, and yielding. But water will wear away rock, which is rigid and cannot yield. As a rule, whatever is fluid, soft, and yielding will overcome whatever is rigid and hard. This is another paradox: what is soft is strong.
