Network more, both online and off. Join LinkedIn groups, maybe professional organizations too.
Translate more, even if it’s not for a job, but not for free! Say no to shady projects/dubious “translation tests”!
Get out of the house more, try to work in libraries or cafes, maybe even parks, esp when the weather becomes warmer.
Back-up/organize work better, so translation samples of any type can be found quickly and less time is wasted finding stuff to send to potential agencies/clients.
