Staying at the cutting edge helps, I picked up an Angular job when it was brand new, and thus nearly impossible to hire an expert on. Also I try to find stuff that is similar to where I have worked. For example same technology stack, different industry. Or different technologies, same industry. This way my expertise can keep me relevant for the company, but the contract is still interesting enough to keep me highly motivated. This all sounds great in theory, the truly hard part is getting to know enough people so that there are enough jobs on the table that I have any choice.
