Sitting a survey and being paid for it is a relatively new idea in the mass market, although it is true to say that people have been paid for giving their consumer opinion in one form or another for some time now. Making it an actual job is something that is less common, and will take a great deal of commitment to something which, after all, still entails simply sitting clicking buttons. Is it really possible to fill in surveys for a living?
It would be incorrect to say that you could have a comfortable living just from sitting in front of a computer doing surveys for even eight hours a day. There is a limit to the number of surveys on the internet which pay in this way anyway. What you can do is make significant extra income by diligently participating in as many surveys as you can, and qualifying to take premium surveys by doing so. With an additional income, you can make your existing income from daily work look a lot more healthy. If you can set aside the time to do a lot of surveys in your spare time, then you can have a quite impressive side income.
Some survey sites allow you to accumulate money which will be totalled up until it gets to a certain point, at which they will issue you the money as a bank payment and increase your bank balance. If you do this regularly enough, you can soon accumulate enough money to spend on something you have wanted for a long time, but have never been able to justify spending your wages on.
