I don't know how I get work, but I always seem to be busy (for the past four years of freelancing at least).

Main thing is to put the word out. Have projects of your own. Offer advice freely. Be helpful. I normally have more work than I want and can be fairly choosy.

But I've got to admit, if it all dried up, I'm not sure how I'd go about 'looking' for work. (that said, I'm not sure I'd want to)
