Usually skills you have will help a lot. Find time to study how to do web sites, write articles, edit photos, programs, and even PPC will do.
If you want to invest, try to have a website, affiliates, and the like. Also, try adding google adwords and adsense to your site. This will help a lot. I make $14 everyday just for this stuff. Adding a bunch of PPC and some sidelines, I am making $60 per day.
