The way people make gil is finding something they can do that other people want. So, ask yourself, what can you do?
Otherwise, it's going to be something like, "level a craft." And if you're willing to take that on, great, but it can be a really long and expensive road, and markets always change. Even magic fishing isn't going to make you a lot of money for a while.
