Become a proofreader. All kinds of businesses hire professional proofreaders to look over their copy and content for errors before they publish. This side hustle is one that could work for nearly anyone since you can work from home provided you have a computer and an internet connection. You can find online proofreading jobs through websites like Indeed.com and FlexJobs.com
Go undercover to local stores, look around, take notes and sneaky pictures of stuff doing nothing, fill in the questionnaire afterwards and get your cash. You can get mystery shopping assignments via Mobee app (typically the payments are not that big, yet the tasks you need to do are simple too) or get an account with Marketforce – a more established website where you’ll need to carefully fill in an application form and pass a review process. The potential earning are much bigger.
