You'll find my course and class recommendations for training for work at home. Many I have taken myself. And some even offer free online mini-courses so that you can get a feel for a career before you head off in that direction. As well - I love covering the topics of ways to make money online and SAVE money that don't necessarily fall under the "employment" umbrella - but can earn extra cash. I'm on a budget and trying to pay off debt - just like most people. So whenever I come across a great new way to save or earn cash -- you better believe I am going to share it with you. And I promise... no crazy "at home stuffing envelopes" nonsense!
You can absolutely use websites like eBay and Etsy! Try listing some items and making a professional Facebook page for yourself with a link to your eBay/Etsy pages. Then share the information with friends and family and get them to spread the word to people they know. Also, make sure that you have detailed descriptions and multiple pictures with anything you list online. This will help your listing show up in keyword searches, and you are more likely to sell something if the buyer knows a lot about what they are looking at.
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!
