Earnest (refinance your student loans): Same idea as above but on your student loans. There is $1.4 trillion in student loan debt outstanding. When you have student loan debt, it can make it hard to get ahead, invest, or to buy a home. If this sounds familiar, refinancing the debt can not only help you pay it off more quickly, but it can save you money on interest too.
One of the cool things about Google AdSense is that it's so easy to get set up. If you have a blog or website, you can sign up for a free Google AdSense Account. From there, Google will give you a unique code that you will paste onto your website. Google takes it from there, tracking your page views, traffic, and earnings on your behalf. There is no upkeep or maintenance to get this thing going, which makes it a no-brainer if you have a website already.
