Again, if your blog has a large reader base, then businesses may be interested in paying you to review their services or products. Not only will you get a free trial using whatever these businesses are selling, you will also get a fee for writing them a review and posting it to your site. Paid reviews (and other paid and sponsored content) can be big money, so advertise this service on your contact page to generate business.
If you're looking to address some immediate financial needs, then the app economy is likely right for you. Thanks to the global sharing phenomenon, launched in part by our smartphones and ever-burgeoning global connectivity, you could easily opt for some quick active income by using well-known apps. From ride sharing to deliveries and even quick tasks, there's an app for that today, as the saying goes. 
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!
It’s free to join the SellHealth affiliate program, though you do have to apply and be accepted before you can start promoting their products.  Once you’re accepted, you’ll have access to a number of tools, graphics, banners and more that you can use to promote SellHealth products.  The sales are actually made at company-owned Websites, which look professional and handle all of the selling. Commissions vary, but the base rate is 30% of all sales and upsells, and SellHealth says you can earn up to $350 per sale.
eBay: eBay is one of the most popular websites in the world, period. That means it’s a great way to attract lots of eyeballs to your unwanted items, fast. Initially designed as an auction site for DIY sellers, it’s now primarily a venue for fixed-price (though often heavily discounted) sales by professional merchants. Still, as long as you include high-quality photographs and thorough descriptions in your product listings, you can likely break through the noise. eBay’s fee schedule is complex, but as a general rule, expect to lose 10% of your final selling price to the site’s commission.
I'm just starting at Clickbank, so I'm a total newbie, but if I want to follow this strategy can I do it promoting just one product, for example, Category>Health & Fitness ---> X product. Then, should i start a blog or something like that where i can talk about things related to the product subject? if so, do i have to start making entries about this recurrently? or I can opt for just making an article with a free ebook in exchange to user's e-mails and follow the process?
