Everyone talks about how much money they make and their RPI. But between finding models, shooting enough images per month to keep your income growing, running them all through Photoshop, figuring out keywords, dealing with iStock's disambiguation and then submitting to ten different sites, there's a lot of stuff for a microstocker to do. How much time do you spend doing it?

I'm also curious what keeps you going. That you love photography is probably a given But instead of putting your stuff on Flickr, you're scanning model releases and thinking in keywords. Is it the monthly paycheck? Is it the thrill of someone liking your work enough to buy it? Or are you just addicted to watching the sales counter as it keeps climbing up...
