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!
If you wish you had a little more money in your pocket, you’re not alone. Fortunately, you have a variety of options when it comes to making money. Doing odd jobs is a quick and easy way to earn money. Similarly, reselling items or selling items you make can earn you extra cash. As another option, earn money online by writing a blog, freelancing, or doing online surveys.
