There are numerous printing companies that will print your designs onto not just T-shirts, but also hoodies, hats, posters, cushions, bags, and phone cases, to name a few items. These businesses also offer fulfillment services. This means that you promote the merchandise on your own site and once you sell a product the printing company will not only print your design but also send the item directly to the buyer. So all you have to do is concentrate on the marketing and selling of your products, and the fulfillment company will take care of the rest.
There’s an excellent chance that you have one or several musical instruments sitting in storage that haven’t been used in years. Perhaps it’s a leftover from when you were in school, or even from your days playing in a band. Whatever the reason that you have it, it’s probably worth money if you can sell it.

Once you find the perfect domain name to resell, you can market it on Flippa.com for a flat fee.
If that sounds like too much technical information for you, there is an easy button – Google’s advertising platform is as simple as signing up, enabling (on Blogger) or pasting a small code on your website, and allowing the advertisements to automatically roll in. The problem with this program is that you don’t get any commissions – and you don’t get to control the ad content. This is useful for some, but powerful users will want something a little more robust.

Find a profitable niche. Starting with your interests, write down as many niche ideas as you can. Think about topics people might search online. Ideas include passions (like surfing or body building), fears (like spiders or speaking in front of crowds) and problems (like getting out of debt).

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.

There is no upkeep or maintenance to get this thing going, which makes it a no-brainer if you have a website already.
