How Do You Maintain a Network Between Searches?
Lightly and honestly. The failure mode is going silent for three years and reappearing with a favor to ask; the fix is two or three genuine touches a year per contact. Congratulate promotions and launches, send an article that made you think of them, share a job lead that fits them, or just reply to something they posted with an actual thought. Keep a simple list of the twenty people whose careers you care about and skim it monthly. When you eventually do search, the message isn't a cold revival, it's a continuation, and asking for advice from someone you've stayed warm with feels normal to both of you.
