I write my sister a letter every day and somehow manage to ramble for a few pages, but when I write to those on my “occasional letter” list, I sometimes have to think before I can even fill a notecard.
I see the same principle in action with coaching clients: when I meet with them weekly, there is always more to discuss than time allows, but when we switch to bi-weekly or monthly it takes longer to get into meaningful topics. This is also true for 1:1 sessions with supervisor/employee, meetings of project groups or task forces, and most other encounters.
Frequency — and then by default, recency — allows for more depth, emotion, and substantive interactions. You spend less time ramping up and returning to where you ended and can have greater continuity and flow to your engagements. If you find yourself starting with “where did we leave off…” it’s time to connect more often.
