How much is enough?

Is 30000 enough? How about 40000, how about 70000, or how about 100000? Who does want more money as long as you earned for it. I am really tired my working environment. I am very stress and that has came to the bottom my line. I doesn't pay enough for I did, what I cared and what I contributed. I gonna look for someone and somewhere who I can work for and see what I did.
