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. 
This is a site where you can sign up to transcribe audio files. They pay new transcribers $20 an audio hour (remember this is quite a bit longer than a regular hour). You can get in with no prior transcription experience, you just have to take a short test which I believe you can retake if you fail it the first time. You only need $1 to cash out, hitting the withdrawal button for payment any time as long as you have $1 earned. It might be one of the best ways to make money fast today if you can pass the skills test.
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.
