Odds of Hanging On
Burnout rates are high, especially since you need to do a lot of shops in order to add up to any kind of money.
However, if you don't mind the lousy wages and you get into the groove, you can keep mystery shopping for years and years to come.
There are oodles of mystery shopping companies out there for everything under the sun. If you start to get bored doing one kind of shop, move over to shop something completely different to keep things feeling fresh.
