Familiarity lowers value. If you are always available, you become ordinary, and ordinary is treated casually.
Use absence as scarcity. Withdraw after success, not after failure, so the gap reads as demand rather than rejection. Let others feel the inconvenience of not having you. That inconvenience rewrites your price in their mind.
Return with timing: when decisions are near, when your name is being discussed, when need is rising. Vanish too long and you are replaced. Vanish briefly and you are remembered.
Absence must look intentional, not emotional. The point is control of access. When your presence feels chosen, it carries weight. When your presence feels automatic, it becomes background noise. Distance renews appetite, then you re-enter on your terms.
