How we can earn emoney

I have made money online in the past. Certainly not the rags to riches stories I have read. I am not back at it trying to make an extra income. I use several sites and rotate between them. They are surveys, writing articles, writing reviews and I am recently looking at affiliate marketing. There are so many places to earn money on the internet but do beware. I have not spent any of my own money on products and am doing just fine. Watch out for scams!
