Taking surveys online for large companies could get you to earn a good extra income, you don't need to think about it that much, you just need to fill up form and answer with great honesty, and of coarse if you want to earn more you need to exceed effort and trust me its all worth it in the end.
The best part about this is that you have a lot of option in doing these, you could do this as sideline doing this while working or you could do this full time from anywhere and even at comforts of your own home, no deadlines, no boss to nag at you, no financial risk and it's stress free.
Now do you think it's quite worth it to do this job, they don't require much form you except your honest opinion and your time and dedication, earning something extra for the family and something extra for yourself. This is an opportunity, what you've got to lose?
