We reject the straightforward solution as too simple to work, then overcomplicate ourselves into burnout. The plain answer was right all along.
The idea
Every other month I teach A/B/C prioritization to about 60 glowing boxes on Zoom, and I get a lot of nodding. Then the question always comes: "OK... once I do that, what's next?" That's the midwit trap. We look at a straightforward solution as too foolish to be effective, so we pile on tools, ideas, plans and to-dos, burn ourselves out and set ourselves up for failure. Then we realize the Jedi-knight solution was there all along: keep it simple. Simple doesn't mean easy.
How to do it
Before you build more structure, go back to the top of your list.
For the people who matter most, check the basics. Do you have their birthday, home address, office address and kids' names?
Fill in everything that will help you deepen and maintain those relationships for years. That's your "what's next."
Example
I once spent two hours organizing my Tupperware cabinet because I thought I needed a perfect system for everything. The opposite discovery, that it made no difference whether I separated my laundry into lights and darks, brought me real relief. Same with your network: before you create a tag for "working parents with three children who attended an open house in West Oakland and play banjo," make sure you know your A's kids' names.
Simple Systems Win: The tactic that works is almost always tiny and simple, and simple still takes consistent effort. Remove things before adding them.
Choice Overload: The more options and categories you face, the less likely you are to act. Cut the choices down, starting with your CRM tags.
A/B/C Spheres: Sort everyone into three tiers by gut feeling (love, like, don't know) and spend more time on A's than B's, and more on B's than C's.
The A-List Essentials: For your top people, decide what you'll actually use (birthday, address, family names, outreach interval), then fill in only that, before building fancy tags.
