making any money off clixsense grid?

Tweet

I have already been on clixsense long enough to make a payout and I am well into the next one. I have no real complaints, it seems to be a legit enough site and all. But I click the grid my allotted 30 times every single day and never win anything! When I first signed up I won like 10 cents. I have not one a single penny since then! I am a moron of sorts I guess because I figure if I don't click it any more (which I am tempted to do) then I won't be wasting my time. However, if I don't click it any more there's also absolutely no chance of winning a dime! As long as I click even though I never really win anything... there's that minimal chance that I might win a penny or two more!! What do you think, to click or not to click?
