Make sure you have permission for everything you choose to sell. You don't want to sell something your parents still want! Also, consider an object's personal value before you sell: even if something is only worth ten dollars to someone else, it could have sentimental or nostalgic value for you or your family which is worth significantly more than ten dollars.
As always, you need to be particularly careful about advertising or doing any other business online. Make sure your parents are aware and approve of all the ads and forums you’re using—for example, if you’re advertising on Instagram and Facebook, make sure your parents know about both of these social media portals and can help you regulate them—and have them come with you if you’re going somewhere to mow lawns or babysit for the first time.
Most teens don’t want to be doctors these days, they want to be Youtubers. And why not? It is a lot of work but you don’t have to go to years of school and you can start now.

Most people want a few more dollars in their wallets. But between an employer and family, the time most of us can devote to a second job is severely limited. Running a small side business can provide a few more options: you don’t have to show up at a set time and you can use skills you already have. Not all will be perfect for everyone, of course, and I’m sure that you’ll have a few ideas of your own after reading this list. If you’d like to share any other business ideas, please add them in the comments.

Do yard work. Many people are too busy for basic yard maintenance, but they don’t want their homes to look unkempt or neglected. These people are often more than willing to pay someone to mow the lawn, rake leaves, or trim hedges, especially if they can hire a neighborhood teen or family friend. Start by asking your friends and family if they need help, and, if you don’t get enough business, post some signs around the neighborhood offering your services.

The best way to take on an evening side hustle to make some extra cash is to establish your strengths and figure out what you enjoy and how much time you can invest. The above business ideas are just a few examples to try, and there's a huge list from which to choose, so start searching online and find your side hustle to make more money in your spare time.

Double check yourself, before you double wreck yourself. Make sure everything you send to a company, whether a résumé, an email or a portfolio, is good to go. Double check your grammar and wording, and for God’s sake use spell check! This is especially important when it comes to the company’s name. Don’t spell their name wrong and be sure to type it how they type it (e.g. Problogger, not Pro Blogger).
Great post, thanks for sharing. I have recently started researching android apps for a little side income. Because I find that the majority of newbie marketers get stuck at hosting costs. Especially in my area because of the exchange rate. And I have to agree that blogging is indeed an excellent way to make money online. But you’re quite right. It is a lot of work.
