UserTesting’s website testing gigs do require focus and rigor, but they’re far shorter and don’t need to happen simultaneously, making them much easier to fit into your schedule. They don’t pay quite as well as game testing, though. If you’re diligent, you can reliably earn $20 per hour, though the overall work volume is sometimes thin. You need a decent, relatively new computer or smartphone to complete tests.
I think you can do well with this business if you start with people in your neighborhood and ask them if you can have an opportunity to perform this service for them. Word of mouth will travel fast if you provide a good value. I think the key to doing very well here is to package your service.

The ego is the driver making the decisions. It decides between the devil (the id) and the angel (the super-ego) on either shoulder (yes, all those cartoons you've ever seen are partly true).
