You should mention what kind of skills you've got. There are plenty of things you can do but most of them require skills. The skill, of course, has to be valuable to others.
For instance, if you're good at writing, finding a decent content writing job won't be all that tough. People will also pay for your graphical artworks if you're good at graphic design and stuff like that!
The point is, getting money online is possible as long as you've got the right skill to offer.
