For me it was keeping a client happy and then always saying yes to introductions that would eventually be made. Even if the project wasn't a good fit I'd say yes to the meeting just to build a connection and hopefully point the person in the right direction.

Or for non-clients, just taking time to ask how they're doing, what's new or really showing any spontaneous interest in their life or career. It's amazing how many times I checked in with people that it would remind them of someone they overheard needing consulting.
