How do I keep professional relationships strong over time?

You are good at the beginning of relationships. The meeting, the spark, the first real conversation. Keeping them warm over months and years is where it gets uneven, and that is true for almost everyone. Beginnings are exciting. Tending is quiet work. Relationships do not fade because of one big failure. They fade from small silences, from the message you meant to send and did not. Depth is not built in grand gestures. It is built in remembering, in showing up when there is nothing to gain, in the small steady signals that say you still matter to me. Pick three people who mattered to you and whom you have let drift. Reach out to one this week with no ask attached. Just a note that you were thinking of them. Do that until it is a habit. Sustained relationships are just this, repeated.
