I think a personal CRM should include knowledge of Dunbar's number.[0][1]
Like,
"You are spending too much time with C people. Is C person Andrew now a B? B people like Joe and Jane need more attention."
"You could use another A relationship. The following B people might be good candidates based on your contact frequency."
This is mostly tongue-in-cheek, but it is often true that people don't attend to relationships with apprppriate priority. And, knowing your situation with regard to various relationship levels provides insight for growth.
