If you have a flair for designing cool images, don't bother about creating your own inventory. As long as your design can be printed on a product, you can pocket some money. You can upload designs on various Websites such as CafePress, and if somebody orders these designs, the company will print them and distribute the products. It could be designs for T-shirts, hats, bags, books, posters, calendars, greeting cards, etc. You will receive a commission for each sale. Other such sites include Lulu and Zazzle.

However, not matter what method you choose to make money online, understand that you might be able to make some money fast, but for the sizable returns, you'll need significant sweat equity. However, a year from now, you'll be happy you started today. Remember, time is far more valuable than money. Focus on creating passive income streams that will free up your time so that you can quit the rat race and focus on the things that matter. That's the important thing here. 

Blogging is something that requires patience, persistence and discipline. It may mean writing everyday for over a year before you really start to see any money from it. There are exceptions to the rule, but from my dealings with other bloggers, it seems to be pretty common to spend one or even two years building your blog, your brand and your authority, before making any serious amount of money.
Since time is the most precious commodity on this earth, invest the time at the front-end so that you can reap the benefits on the back-end. This means putting in a bit of sweat equity and not getting paid today. Rather, you'll get paid somewhere down the road. And you'll continue getting paid whether you keep building that passive income stream or you stop. It's obvious that this is the preferred route, but clearly the road less traveled.
One thing that you have to keep in mind is that the surveys do expire after some time. This app in your phone does nothing most of the time, but every now and then it displays a notification that there is a survey it would like you to complete. It must be done within a certain time period, i.e. in the next 24 hours. As long as you check your phone once a day, you won’t miss the surveys.
