However, like anything else truly worthwhile, apps require a significant investment of your time or money upfront. If you don't have the skills, then you have to hire someone who can assist you in creating a great app. But first you need to come up with an idea that will sell. Do the proper market research and analytics to come up with the right app.
To make money easily, look for odd jobs like dog-walking, yard work, or running errands for elderly neighbors. Sell off old things you don’t need anymore, like books, CDs, DVDs, furniture, and clothes. Use your talents to make money by selling crafts, taking photos at events, designing web images, or starting a blog about something you love. For a quick side job, sign up to participate in focus groups in your area, complete online surveys, or look on websites like Craigslist and Fiverr for interesting, unusual gigs.
But cutting costs only goes so far. Unless you already make a lot of money and spend like a bon vivant, most people can’t eke out that much more from their budget by decreasing expenses. Plus, the more you retrench, the more your quality of life suffers. (It’s all relative, though — certainly some overspenders could actually improve their lives by tempering their expenditures. Here are 101 ideas for saving money.)
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.
