This thread got no atention, but i'm gonna write here cause i think it's an interesting subject.
Obviously first is getting a job. You have to keep yourself into a job, and better be a job that allows you to improve finantially. Wageslaving in mcdonalds is not a way to go.
Second should be saving money, all you can. And investing that money you save into something that can get some profits at medium-long term.
If you can save enough to buy a place to live, that's another big investment that should be taken very seriously.
