I personally like this one for some spare cash. It does not take much to earn an extra $20 – $50 a week. Some claim that they are able to make a living by dedicating their time to different jobs at mTurk. You will have to go through a learning curve, but once you get comfortable, you will find plenty of good and interesting HITs (Human Intelligence Tasks) to work on.

However, with online employment comes fraudulent companies who scam job seekers into signing illegitimate offers. "There is currently a 61-to-1 scam ratio among work-at-home job leads on the internet — that is, for every legitimate job, there are 61 scams," says Christine Durst, cofounder of RatRaceRebellion.com and consultant to the FBI on internet scam.
Online business is how I’ve made a living since 2003 and what has helped me retire early.  I make over $40,000 a month through my blog. You can create your own blog here with my easy 15-minute step-by-step tutorial.  You can start a blog for as little as $2.95 a month (less than a cup of coffee!).  Create a blog and leverage it into affiliate sales or product endorsement deals.

As far as Poker goes (at least for Texas Hold’em), I’d recommend sitting at a low stakes table (1/2 no-limit is the lowest most places have) and merely being observant/make casual conversation at the table for a while until you feel comfortable. If you’ve never played, just tell the dealer and they’ll be happy to help you out (most players will notice if you haven’t played before anyways so you’re not really at a loss there). Just play “tight” (a small range of strong starting hands) and that’s a pretty good place to start!
The best part? You get to put a smile on someone’s face — and you get paid to do it. Though exact wages will vary, Instacart Shoppers can earn as much as $20 per hour. If you committed to a typical 40-hour workweek, your compensation would come in at just under $40,000 per year (without taking into consideration expenses like gas and wear and tear on your vehicle).

The first follows the startup path we outlined above: You have a disruptive idea for an app or piece of software, you validate the idea with real customers, and then raise money to hire developers or a development studio to build, launch, and scale your software.
