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. 
Donating plasma can actually work out better than selling your blood.  It takes longer to donate plasma because they will put your red blood cells back in your system. The upside is that you can donate plasma as much as twice a week and you can make anywhere from $40-$60 per donation. You can make that $100 in less than a week if you can stomach the needle. 

Take advantage of tax laws if you're self-employed. Money saved on taxes is still money saved. You may be able to deduct many of your business expenses (use of your home, use of your car, office supplies, etc.) if you keep good records. You may also qualify for tax breaks, such as deducting your health insurance premiums on your tax return. These laws are in place to encourage commerce and business growth, so don't neglect their benefits especially if you want to make money.
Redefine wealth. In studies of millionaires, people are surprised to learn that most millionaires aren't doctors, lawyers, and corporate leaders with big houses and fancy cars; they're people who religiously live below their means and invest the surplus into assets, rather than liabilities.[4] As you're taking the above steps to make more money, keep in mind that increased income does not necessarily equal increased wealth. Most people who flaunt their wealth actually have a low net worth because their debt to asset ratio is high--in other words, they owe a whole lot more money than they actually have. All of the previous steps have outlined aggressive strategies for making money, but you'll never get anywhere if you have a hole in your pocket.
Great article, I have tried a few over the years. I had a side business cleaning offices for years. It did great, but I hated never being able to take more than 3-4 days vacation, so I eventually gave up. I tried MTurk, but if you multiplied my earnings on an hourly basis, it was a little over $6/hr. My blog is much worse, probably less than $0.25/hr.
