Waiting tables and bartending are good ways to make extra money, but it’s not exactly if the work was easy. And if you don’t have any experience good luck applying at the nicest place in town, most restaurants require experience. Also if you have problems dealing with demanding, hungry people – STAY AWAY! The hours are late, sometimes you won’t make any money. Especially right now, starting at new place will be difficult, if you can get hired expect to be the first one cut every night (aka less money) as those with seniority will want to stay. It still is a good deal though. I’ve put myself through college (chem major) without loans, never lived in the dorms, and I have about 10K in the bank. I will continue working in the restaurant biz even after I have a “Real Job,” the extra 10-15K/year for part time work is worth it.
And yes, if you do commit to something like blogging, or writing and freelancing, you can and will make a living (you could even make way more than you could ever at your day job. That said, no matter how much time and effort you put into things like surveys, paid to click sites and things like that, they are not gonna replace your day job. They are just an attitudinal income generation options that you can use in your free time.
For example, let’s say you signed up to become an Amazon Associate so you can make money as an affiliate of Amazon. You then create a gardening video showing people how to plant a small tree. Find the exact shovel you are using in the video, on Amazon, get your affiliate link and put it in the description of your video so people who are interested can buy the same shovel on Amazon. For every person that buys the shovel, you earn a commission.
