Welcome to gaia
it's true that the mp is just INSANE
next to posting, playing games and etc, you can sell art. People sometimes even tip. Or you can do other stuff like coding or fanfics and etc. for gaiagold.
Atleast in the gaiagold shops there are some decent items to make a nice looking avatar. And with luck people even donate something to you. Or you can win with giveaways. smile
