There are many opportunities to work online, but you will first need to get some skills and learn something, so my suggestion here would be to choose some field that is interesting for you, find as many good tutorials and blogs about it, and start learning. Only after you get at least some basic understanding about that topic you can move forward and open your own project and start earning from it. But it needs to go step by step.
If you have good writing skills - you can write from any place in the World online and earn money. This is a proper movement to success!
