Kairos is the right moment, as opposed to chronos, clock time. Good timing persuades.
Greeks had two words for time. Chronos is clock time, ticking along. Kairos is the right moment, the opening an archer waits for. Orators were trained to sense kairos.
Asking for a raise right after you closed the biggest deal of the quarter. Kairos.
Follow up with a lead the day you meet, not a week later. Timing is kairos.
