For me this started out as an experiment to find legit sites that actually paid. I'm signed up for a couple dozen survey and GPT sites, as well as a handful of PTC sites I'm experimenting with different strategies, and got into penny auctions most recently (which I made it a rule I could only support that by using other online money I made). I was very surprised how much I was able to make and learned there was an ebb and flow to things (feasts and famines). Now I'm taking this knowledge and trying to advise friends and family who want to make some extra cash, to provide them the information/strategies I learned to make best use of their time.
This year I made it my goal to see if I could pay for Christmas using nothing but online money I made (cash, gift cards, penny auction wins, etc) - and thus far, I pleasantly surprised to report I think I'm going to make it just nicely.
One thing I found out is a lot of people I provide this information to, all are looking for a little extra cash, but very few actually follow through to sign up. This site and others like it can help you make some extra cash, one just has to decide to do it and be consistent with working them. When I first started, I put in a lot of time on each new site too, but once I got the hang of the site - learned what worked best for me and what didn't - then I found I started spending less time on the sites as I was able to work them more efficiently. Now I may spend an hour in the morning before work, and may be a couple hours after work, and I'm done with all my sites. Only days where I seem to qualify for every survey gets long - but those are rare days.
If you think it'll be worth working this site to make a little extra cash, I say give it a couple months. Try out the different items - surveys, tasks, videos, offers, etc - find out which ones work best for you, then later just limit yourself to those target items. Then you'll find you're in and out and on with your day.
Good luck to you!
