Should you just stick to one thing?

personally I think 1, 2 or maximum 3 sites. I think if you bog yourself down with too many sites you kinda freak yourself out into how much time you should spend on each to make a good profit. I so far stickby slicethepie, ciao, and dooyoo.

I agree with Bead on this one. You need to explore your earning options widely to determine what is best for you. If you find something that really works for you, then you might want to narrow it down, but it'd be foolish to not first check different opportunities out. Imagine, for instance, if you focused everything on working on a site that turns out to be a scam -- all your time and effort would be worth nothing!

I think when you first start trying to make money on the internet it's good to spread yourself around to different types of sites. As you get acquainted with them, you will see which ones pay, which ones suite your individual talents, and which ones are worth staying with.
