As a programmer, it's always a few months of work before the client stops spending on development. At that point, I can go up to 3 months without work, which means high anxiety because if I wasn't able to save much, I have to scurry around trying to find work. Sometimes I get a referral or two but it'd be nice to have about the same stability as being employed.

How do you programmers here manage to land a constant amount of work while freelancing?
