Though this may not be an ideal situation, taking in a long-term roommate can drastically reduce your housing payments. The best roommates are those who you already know to be relatively friendly and like to maintain their current living space in an orderly fashion. If you do not know of anyone who fits the bill, you can usually find someone either on Craigslist, or a few other “roommates wanted” websites.
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.
